OriMaster Orifice DP Flowmeter
By ABB Instrumentation
www.abb.com
 ABB Instrumentation’s OriMaster DP flowmeter is a one-piece unit that includes both the orifice plate and a differential-pressure meter. It comes fully factory configured and pressure tested, solving many of the problems associated with sizing, selection, installation and operation of conventional orifice-plate installations. The flowmeter comes in two versions — one for volumetric readings (OriMaster V) and the other for mass flow (OriMaster M).
The OriMaster eliminates the need for users to source and install a separate manifold, transmitter and impulse piping, typically cutting the cost of installation and commissioning by up to 50 percent. The flowmeter’s short integral impulse paths simplify installation. By eliminating up to 80 percent of the potential leak points, it greatly reduces both fugitive emissions (at threaded connections and compression fittings) and also the metering errors caused by such leakage.
Installing the OriMaster is simplified by its wafer design orifice carrier assembly, enabling it to be fitted into an existing space between standard pipe flanges with minimal disruption to the surrounding pipework.
Both the volumetric and mass-flow versions of the flowmeter have HART communications. The mass-flow version has an additional option of Profibus PA, Foundation Fieldbus or Modbus communications.

UNCD Mechanical Seal Faces
By Advanced Diamond Technologies, Inc.
www.thindiamond.com
 Advanced Diamond Technologies’ UNCD Faces are standard carbide faces for mechanical seals that are coated with ADT’s brand name ultrananocrystalline diamond. UNCD, a phase-pure diamond film, was originally invented at the U.S. Department of Energy’s Argonne National Laboratory, leveraging over $10 million in basic research.
ADT’s innovation with UNCD Faces is to provide diamond film that is exceptionally smooth, while maintaining the flatness of the original silicone carbide face. UNCD can be manufactured so smooth that it can be run against soft carbon counterfaces. In addition, UNCD offers excellent chemical inertness and has high thermal conductivity.
ADT offers UNCD Faces affordably because of its achievements in developing a scalable and highly reproducible manufacturing platform. This gets diamond out of the realm of being a precious gem and into the realm of being a performance engineering material.
Seal companies have been searching for a way for over a decade to take advantage of the outstanding benefits of diamond. The innovation of UNCD Faces is that UNCD is phase-pure diamond that is grown on the surface of a silicone carbide face. Unlike diamond like carbons (DLCs) or conversion coating processes, UNCD offers the superlative properties of real diamond, which is much harder than DLCs or silicone carbide.
Application Note: Seals incorporating UNCD Faces were named to this year’s R&D magazine R&D 100 list. In partnership with John Crane Inc. and Argonne National Lab, the UNCD Faces solution was rigorously tested as part of the award-winning solution.
170 Slurry Seal
By A.W. Chesterton
www.chesterton.com/slurry
 A.W. Chesterton’s 170 Slurry Seal is a shaft-based device with a nonclogging pressure-plate design. Seal faces are hydraulically balance, with the springs located entirely outside the seal. The seal is also designed to operate with no flush water. Other seals on the market that offer the ability to operate with no flush water, generally have springs located inside the seal, presenting the potential for clogging. The seal offers consistent flushless operation up to 40 percent solids.
Application Note: The 170 Slurry Seal was recently employed in an application that was experiencing a mean time between failure (MTBF) of one month prior to installation. After replacing its existing seal with the 170 Slurry Seal, the user has increased its MTBF from one month to 24 months and counting. The entire plant is now replacing each seal that fails with the 170. Further, it has improved the environmental friendliness of the application by eliminating the use of flush water.

Laser Flow-Sensor
By Digmesa AG
www.digmesa.com
 Digmesa AG’s patented liquid flow sensor technology measures flow using a laser perpendicularly oriented to the media flowing through a straight glass tube. This nonintrusive sensor concept is capable of measuring flowrates in the 1-20ml/min range with response times of ~20ms and accuracies better than 1 percent full scale. The flow sensor is able to measure various types of water- or alcohol-based liquids without the need for recalibration after it is factory calibrated.
Application Note: During integrated circuit (IC) manufacturing in the semiconductor industry, photo resists and other chemicals have to be dispensed on the surface of a thin slice of semiconductor material, typically a silicon wafer. The new Laser Flow-Sensor is used to monitor the dispensed volume in such applications. Every produced wafer has an average of 30 layers requiring 30 manufacturing cycles, with each cycle consisting of multiple process steps of coating, exposure, developing and etching, and possibly doping. Very advanced wafers use up to 45 cycles. Every manufacturing cycle increases the cost and value of the wafer. For the critical layers, the last 10, it is very important to ensure the exact amount of chemical is dispensed, so a monitoring device is needed.
Future plans will aim to reduce the costly photo resist process, which figures to make the need for a flow sensor even more critical. The Laser Flow-Sensor is designed to overcome such disadvantages.

Flow Hunter with Xducer 06 Ultrasonic Flowmeter
By ECHO Process Instrumentation, Inc.
www.echopi.com
 ECHO Process Instrumentation’s Flow Hunter electronics with the Xducer 06 transducer offer open-channel ultrasonic flow measurement accuracy of +/- 0.01 percent of measured range. The meter is designed for measuring flow in flumes and weirs with an extremely reliable output for billing and monitoring purposes.
The Flow Hunter electronics with the Xducer 06 sensor operate at 80kHz, which is double the industry standard of 40kHz. This is important because the resolution of a transducer is dependent on wavelength; the higher the frequency, the smaller the wavelength and the smaller resolution of the measurement. Thus, a 40kHz transducer can only resolve down to three millimeters, whereas the 80kHz transducer is better than one millimeter.
ECHO’s ultrasonic technology is based on radial-mode piezoelectric resonators with unique fascia material transducer technology. This produces an echo pulse with no side lobe energy loss, which is an inherent weakness to traditional thickness mode transmission. Also, the technology employs automatic gain control to ensure that the electronic timing circuits see the same signal amplitude regardless of a strong or weak echo.
Industrial acoustical plant noise can often produce sub-harmonic frequencies that overwhelm ultrasonic level transmitters. Flow Hunter uses electronic filtering and precision rectification of echoes at exactly the same frequency as the transmitted signal to eliminate all noise interference.
ElectraTherm Green Machine
By ElectraTherm, Inc.
www.electratherm.com
 ElectraTherm’s Waste Heat Generator (WHG) captures waste heat from almost any geothermal or industrial source to generate fuel-free, emission-free electricity. Built on a skid, it’s both modular and mobile, meaning it’s easy to transport and install as a single unit or in a series. Automated control systems permit unattended operation, resulting in low operation and maintenance costs.
ElectraTherm combines traditional components with patented, cutting-edge technology to create electricity from waste heat. ElectraTherm power systems use a closed-loop organic Rankine cycle (ORC) to create pressure by boiling EPA-approved chemical working fluids into gas. The gas expands in a one-way system and turns a patented Twin Screw Expander, which drives a generator to ultimately put out electricity.
Historically, ORCs incorporating turbo-expanders have not been commercially viable in sizes less than 1MW. By replacing turbo-expanders with ElectraTherm’s patented, robust, low-cost Twin Screw Expander, users benefit from short payback on systems that provide unattended operation and negligible maintenance.
Application Note: In mid-2008, ElectraTherm successfully installed its first commercial Waste Heat Generator at Southern Methodist University in Dallas, Texas. The ElectraTherm Green Machine makes electricity from residual industrial heat that has, until now, gone to waste. With the assistance and cooperation of the world-renowned SMU Geothermal Lab, and the Campus Planning and Plant Operations Department, SMU is hosting the Green Machine as a demonstration site. The ElectraTherm Green Machine employs minimal heat to generate fuel-free, emissions-free electricity at a very low cost — three to four cents per kW/hr during payback period, under a penny per kW/hr thereafter.

Fisher Control-Disk Valve
By Emerson Process Mgmt, Fisher Controls
www.gotofisher.com
 Emerson Process Management’s Fisher Control-Disk rotary valve offers excellent throttling performance. An equal percentage flow characteristic provides an improved throttling range comparable to that of a segmented ball valve. This improved capability allows users to control closer to the target set point, regardless of process disturbances, which results in a reduction in process variability.
The valve body meets PN 10 through PN 40, CL150, and CL300 ratings. Face-to-face and raised-face dimensions meet EN 593, API 609, and MSS-SP68 standards. Line centering clips provide for versatility to mount and align the same wafer style valve body in different piping configurations (ASME and EN ratings).
The Control-Disk rotary valve features an eccentrically mounted disk with either soft or metal seal, providing capability for enhanced shutoff. The interchangeable sealing technology allows for the same valve body to accept both soft and metal seals. The actuator sizing and selection process is improved by simply reading a table for information.
Testimonial: “I was having trouble with my temperature control on several critical loops. Because the temperature control loops could not keep up with process upsets, I ran the risk of having a possible safety alert condition. After installing two Fisher Control-Disk Valves, my temperature control loops react to upset conditions quickly and accurately, removing any safety concerns and allowing me to run closer to a higher set point and gain more output.” – UK-Based Chemical Manufacturer

2-Wire Coriolis Flow & Density Meter
By Emerson Process Mgmt, Micro Motion Division
www.micromotion.com
 Emerson Process Management’s Micro Motion 2-Wire Coriolis meters are loop-powered Coriolis measurement devices that deliver the same high accuracy and repeatable measurement performance as equivalent four-wire Micro Motion Coriolis meters. With compact, integral transmitter housing, Micro Motion two-Wire Coriolis meters require no separate power cabling and deliver multi-variable measurement with a single mA output and HART compatibility for accessing other output variables and diagnostic information.
Historically, Coriolis meters have always required a minimum of four wires – two used for power connection and two for signal transmission. Because of these power requirements, loop-powered Coriolis meters have not been previously thought possible as power is required for the constant vibration of tubes and significant signal processing, in addition to the output of process variables to the control system.
Emerson’s Micro Motion 2-Wire Coriolis meters were developed based on considerable research and sophisticated optimization of the Coriolis sensor and electronics efficiency that allows meter operation with as little as 0.8W of power while delivering excellent measurement performance.

Proline Promass I Coriolis Flowmeter
By Endress+Hauser
www.us.endress.com
 Endress+Hauser’s second-generation of the Promass I Coriolis flowmeter, the straight single-tube design of the Promass 80/83I, provides the expected Coriolis flowmeter outputs of mass flow, density and temperature, as well as in-line viscosity measurement as an optional output. The advantage of measuring viscosity directly in the process is that it is a true reflection of the process conditions and avoids the delay of taking samples to the lab.
The Promass I second-generation also offers improved specifications and better performance. Made possible by revolutionary upgrades such as dual-mode and modified TMB. The meter is manufactured to comply with the highest hygienic standards of 3A, EHEDG and FDA, making it a good fit for food and beverage applications. The integrated software package allows users to derive measurements of Brix, fat content, suspended solids, Baume and percentage of alcohol.
The meter’s TMB counterbalance system has improved the specifications for both mass flow and zero point stability. It is a fully balanced system with a robust design that is not influenced by external vibration. This means density and general flow conditions can deviate from the reference conditions, and the flowmeter will retain specified accuracy. The system is also resilient to temperature shocks; accuracy maintains 0.1 percent even during cleaning periods.
The Promass I design is also the first commercial Coriolis mass flowmeter using two simultaneously driven resonance frequencies. The dual-mode system can actually pick up separate tube vibrations for the mass flow frequency (600 - 700 Hz), and a different frequency for the viscosity frequency (about 900 Hz) and then filter them and analyze them separately in the electronics.

Eccentric Venturi Wellhead
By ENERGYneering Solutions, Inc.
www.energyneeringsolutions.com
 ENERGYneering Solutions’ Eccentric Venturi Wellhead (EVW) utilizes the time-tested principles of fluid mechanics to accurately monitor volumetric flow through a pipe. Designed specifically for the landfill industry, the EVW measures the flow of landfill gas from a well on a landfill.
The wellhead consists of a custom curved PVC flow constrictor placed inside a length of pipe sufficient for creating laminar flow. The custom-curved piece has pressure-monitoring ports at the apex of its curve as well as on the upstream side of the flow. Based on the principles of the Venturi effect, the wellhead constricts the flow of gas through a pipe, creating a pressure differential between the actual flow and the constricted flow. Through many variations and designs, the engineers at ENERGYneering Solutions were able to develop a mathematical model for the pressure differential that accurately calculates volumetric flow through the entire range of flows typically seen in the industry. In addition, the wellhead has been proven to be compatible with any of the commonly used monitoring instruments in the industry today.
Application Note: Early reviews of the EVW have been positive. With installations at multiple landfills around the country, all of the customers have commented on the lack of condensate buildup in the wellhead. In most cases, the EVW has been placed horizontally at the outlet of the well. As the landfill gas is pulled from the well with a constant vacuum, it passes through the EVW, allowing an accurate flow measurement to be taken. In a landfill that might have as many as eighty wells, the maintenance required to empty orifice plates of condensate can become a full-time job. With the EVW, this has been eliminated.

High-Precision Vacuum Control Regulator
By Equilibar LLC
www.equilibar.com
 Equilibar’s Vacuum Control Regulator is designed to provide vacuum stability through various flowrates and pressure ranges.
The regulator works by creating a force balance on a diaphragm directly over the orifices. The vacuum pump, connected to the regulator outlet, is not able to pull the Inlet pressure lower than the reference pressure due to the sealing effect of the diaphragm. Because Equilibar uses a direct sealing diaphragm with no friction or inertia, the response times are much quicker than with mechanical vacuum control systems.
The Equilibar Vacuum Regulator includes a highly sensitive setpoint regulator to conveniently generate this setpoint pressure. Taken together, these two regulators provide highly sensitive and stable vacuums equaling the simplicity and convenience of the traditional products. But, traditional spring-type vacuum regulators have much larger pressure variability (often called “droop”) with changing flowrates.

Gecko Flow Transfer Standard
By Flow Technology
www.ftimeters.com
 Flow Technology’s Gecko portable flow transfer standard provides on-site flowmeter calibration. The system’s EZ-LINK portable interface box and EZ-CAL menu-driven software enable inline comparison calibrations with the unit under test. Designed for both liquid and gas applications, Gecko is an alternative to costly primary standard calibrators for in-house calibrations or verifications. Overall system accuracy is dependent on several factors, including master flowmeter calibration, repeatability and primary standard accuracy, as well as temperature/pressure sensor accuracies. This fundamentally allows the users to tailor the accuracy of the system to meet their needs through the level of master sensors they choose to utilize. The Gecko system can be installed into an existing application utilizing the flow source and actual conditions of the liquid or gas.
A bypass system can be built into the application for ease of installing the master meter with flow straighteners for calibration of the unit under test (UUT). Once the calibration is complete, the master flowmeter can be replaced with a recommended spool piece. The bypass approach maximizes accuracy while minimizing expensive downtime in production schedules. Additional input capabilities for other flowmeter technologies to be used as master flowmeters have been incorporated. This gives the metrologist the ability to choose the flowmeter design best suited for the process. Custom carts, stands and flow loops with multiple master flowmeters are also available.

FT2 View Software allows users to change meter configuration, collect process data or view measurements from a PC or control station. A Palm PDA interface provides similar functionality for “walkaround” monitoring of process conditions.
The instrument directly measures mass flowrate of air and gases, and provides isolated 4-20 mA and pulse outputs for flow rate, as well as a 4-20 mA output for process gas temperature. Mass flowrate and totalized flow, elapsed time, process gas temperature and alarms are displayed on the meter’s 2x16 character backlit display. The display is also used in conjunction with the instrument’s configuration panel to program flow and temperature settings, pulse output scaling, pipe area, zero flow cutoff, filtering, diagnostics and alarm condition limits.
Testimonial: “We use the FOX Model FT2 flowmeter with Modbus communications for measuring our industrial gases. I recently found myself in some ‘soup’ due to the gross inaccuracies we were experiencing with two other manufacturer’s flowmeters. Although I had sent the other meters back to the factory for repair and recalibration, they were never able to achieve the measurement accuracy we require for our processes and services. With an urgent need to get it right and get it done quickly, I installed a FOX FT2 flowmeter and all of our problems went away, period. Now when we have a high-performance application, we turn to Fox for its precision instruments and flow expertise.” — Scott Terdic, Program Manager, U.S. Air Liquide

Sentinel Liquid Custody Transfer (LCT) Ultrasonic Flowmeter
By GE Sensing & Inspection Technologies
www.gesensinginspection.com
 GE Sensing & Inspection Technologies’ Sentinel LCT is a highly accurate ultrasonic flowmeter designed for custody-transfer measurement of crude oil and refined oil products. The Sentinel LCT, with its “install and forget” reliability, is designed to make custody-transfer measurement easier than traditional technologies, requiring less human intervention for maintenance and offering less room for operator error.
Sentinel LCT has a number of unique features that make the meter completely independent of viscosity changes. Whether measuring gasoline or crudes of varying viscosities, the flow measurement is not affected by viscosity or temperature changes. This not only saves time, but also the expense of a proving run. Sentinel LCT uses advanced diagnostics to perform continuous self-checks. A built-in flow computer allows for pressure, temperature and density corrections according to API 11.1.
Computational Fluid Dynamics (CFD) testing of flow scenarios ranged from laminar flows typical of very heavy crudes to highly turbulent flows seen in gasoline and LPG applications. CFD simulations provided the optimal path configuration called the Robust Path Configuration (patent pending) that was proved in a calibration loop, and the results are now filed as a GE patent. Sentinel LCT meets 0.15 percent accuracy with an absolute minimum sensitivity to changing process fluid viscosities.

Signet 4150 Turbidimeter
By GF Piping Systems
www.gfpiping.com
 GF Piping Systems’ Signet 4150 Turbidimeter features accurate and reliable water quality monitoring and quick-and-easy calibration. Compliant to either EPA 180.1 for North and South America and Asia, or ISO 7027 for service in Europe, the new meter is a good fit for both municipal and industrial applications. With its integral pressure regulator, the 4150 features easy one-unit installation and setup. Typical uses include monitoring for potable water distribution, raw or filtered water, wastewater effluent, and aquatic life support.
Turbidity measurement on the 4150 is accomplished through a 90-degree light, which reflects particles as they flow through the cuvette, providing continuous and accurate online measurement. The unit’s replaceable desiccant pack assures a stable environment for accurate measurement, and a built-in backpressure valve can be adjusted to eliminate bubbles that may cause reading errors.
Without the need for tubing disconnection, calibration can be completed easily in less than five minutes. The inexpensive calibration standard allows for both dry and multiple system calibrations without chemical mixing. After calibration, the 4150 is instantly back online once the glass cuvette is placed into the measuring chamber.
Application Note: The 4150 turbidimeter was recently installed on a microfiltration feed from a wastewater plant to a treatment plant. Competitive units used to take the customer one hour per week to clean. If not cleaned weekly, readings would drift off. After three months in service, the 4150 Turbidimeter has maintained stable readings and has not required any cleaning.

Grundfos Multi-Stage CR-H Pump
By Grundfos Pumps Corp.
www.grundfos.com
 Grundfos’s CR-H horizontal multi-stage in-line pump provides an ANSI dimensional solution that will fit into an existing pump and piping footprint. The CR-H pump offers optimized duty points to maximize pump efficiency and minimize internal wear which lowers energy costs, increases pump life, and reduces maintenance.
High efficiency multi-stage design provides pressure ranges that can be expanded beyond ANSI pump limitations without piping changes. The one-piece cartridge shaft seal offers a simple replacement of the cartridge seal and provides seal access without pump removal or disassembly right on the spot in less than an hour. Compared to traditional ANSI pump seal replacement requiring pump disassembly and realignment, and a minimum of eight hours to complete. CR-H retrofit requires no re-piping and can bolt onto the existing baseplate.
Application Note: A field test truck wash facility required a pump that could produce appropriate flow and pressure to operate the nozzle in a multi-step process, involving hot caustic water and various cleaning/rinsing cycles used to clean the inside of large tanker trucks.
Originally, the pumps specified were traditional ANSI pumps with 100 Hp motors. A review of the application prompted Grundfos to propose that the same duty could be achieved with a CR pump with a 30 Hp motor. The truck wash facility agreed to install the lower Hp model and, amazed that the 30 Hp CR outperformed the 100 Hp model, replaced an additional seven pumps over an eight-month period.

Polyfeeder Emulsion Polymer Blending System
By Pulsafeeder Inc
www.pulsa.com
 Pulsafeeder’s Polyfeeder Emulsion Polymer Blending System was specifically developed to handle the diverse mixing requirements of complex emulsion polymers. The Polyfeeder comes equipped with a clear, high-energy mixing chamber followed by a diminishing energy blending cascade, which thoroughly hydrates the molecules without damaging the extending polymer chains. This mixing chamber is clear, allowing quick and easy monitoring of the blending operation.
What truly differentiates the Polyfeeder from other polymer skid systems is its innovative anti-siphon, anti-clog polymer injection lance. This lance effectively separates the polymer from the water interface; the water flow helping to close the valve instead of forcing it open, all the while still being a membrane that can accommodate the occasional solid. This new technology replaces the standard ball and spring checks and eliminates the common pain point of clogging and stuck valves. The Polyfeeder Emulsion Polymer Blending System comes pre-assembled on a rugged stainless steel frame and is available with your choice of a solenoid, gear and progressive-cavity neat polymer feed pump.

CLC Capacitive Level Sensor
By Sensortechnics Inc
www.sensortechnics.com
 Sensortechnics’ CLC level sensor continuously measures the level of liquids and granular or pulverized materials based on the capacitive measuring principle. The sensor is attached to the outside of a container or tank and can measure through almost any nonmetallic wall material. The sensor consists of two electrodes, which form a capacitance with their surrounding environment. The first electrode is mounted to the tank wall and detects any change of the fill level due to a changing capacitance with the process media. The second electrode is situated opposite the first one with insulation between the two. It forms a capacitance with the ambient air and compensates for all changes in environmental conditions, such as temperature and humidity changes.
The CLC sensor is innovative because it is capable of noninvasive, continuous level measurement from outside the container or tank. Previous capacitive level sensors had to be inserted into the tank to measure continuously. If they were placed on the outside of the tank, they could only work as a switch to detect a single liquid level point.
Testimonial: “In our continuous level measurement application with aggressive acid we used a conventional capacitive level sensor with the probe inserted into the fluid. Due to media compatibility problems the sensor had to be replaced about every six months, which was very cost intense and created a lot of maintenance issues. Thanks to Sensortechnics we have finally found a ‘set-and-forget’ solution!” — Bill McNeil, Application Engineer

Smart-Trak 2 with Compod Mass Flowmeter
By Sierra Instruments
www.sierrainstruments.com
 Sierra Instruments’ Smart -Trak 2 is the next generation of the company’s flagship Model 100 line of mass flowmeters and controllers. The Smart-Trak 2 provides a linear sensor, smoother control valve operation, more robust electronics and more control over a wide range of functions. The Smart-Trak 2, coupled with Sierra’s new Compod monitoring software, offers end-users an intelligent flow controller, greatly simplifying basic flow control installations and permitting networking of multiple instruments using open-source MODBUS RTU protocol. A Smart-Trak with Compod is designed to replace more expensive DCS or PLC systems, allowing end-users to automate a variety of processes. Two digital outputs and one analog input can be configured by the end-user, while the Compod monitors the functionality of the MFM and/or MFC and provides diagnostics, notifying users of faults or system upsets.
Application Note: A manufacturer of medical devices must check heart stents for leakage. The process needed to be automated. Expensive PLC-based solutions were proposed, but Compod-enabled Smart Trak 2 proved a much more economical solution. The regulator R1 is set manually to the leak-test pressure. This is usually a pressure above operating pressure of the DUT (device under test). A Smart-Trak MFC is given a setpoint appropriate to fill the DUT at a moderate rate. The MFC’s Compod monitors the flowrate. When the flowrate drops to zero, the pressure in the DUT is equal to the pressure of R1. The internal software in Compod senses the flow has stopped and the Compod closes the valve in the MFC and trips an alarm (light) for the operator, telling him the DUT is pressurized and the leak test is ready to begin. The operator sees the alarm light and opens the ball valve V2 manually. The leak test begins and the mass flowmeter measures the flowrate. As long as the flowrate is below a pre-determined level (flow noise), the DUT passes the test. If the flowrate is above this defined level, the Compod sends an alarm indicating the DUT is leaking and the DUT is failed.

By Tyco Flow Control
www.tycovalves.com
 Tyco Flow Control’s Rovalve PCS17 resilient, seated knife gate valve is designed to support water, pulp and paper, food and beverage, mining and power applications that require positive isolation of media. While there are many styles of resilient seated knife gates, the PCS17 knife gate valve includes an innovative perimeter cartridge seat, providing a combination of features found in few other knife gate valves. The perimeter cartridge seat of the PCS17 provides simplified seat replacement and reduced packing maintenance. It is a good fit for applications where positive shutoff against liquids, light solids and slurries is required.
With its precision-molded perimeter cartridge seat, the Rovalve PCS17 makes knife gate valve repair a cost-effective choice. Most resilient seated knife gates require the valve to be completely removed from the line to replace the seat. Some resilient seats are custom fit and may require minor adjustments or shims to gain proper sealing. Failing to get the fit right can cause premature seat life wear and seal failure. With the Rovalve PCS17, the entire cartridge seat is easily replaced; simply pull the one-piece seat out through the packing box and replace it the same way.
