Plast-O-Matic Valves” PS pilot-operated solenoid valve is available in additional sizes and body materials. Previously offered in Grade 1, Type 1 PVC, the valve is now also available in Corzan CPVC, polypropylene, and Kynar PVDF in sizes from 1/2″ to three inches. The new valve body materials, in combination with either Vitonr or EPDM seals, make the PS suitable for high-purity and corrosive liquid applications. The valve is electrically operated and normally closed, supporting 1,000,000-plus cycle life in liquid process systems requiring high-flow capacity and high-pressure capability. With inlet pressure ratings to 140 PSI, backpressures to 70 PSI, and Cv”s from 5.2 to 80, the PS is a good fit for controlling flow to spray nozzles, high-pressure chemical injections, batch filling, and high-volume transfer applications. All available body materials are resistant to both internal and atmospheric corrosion. The valve uses a Plast-O-Matic-designed PTFE bellows barrier-type dynamic seal, which prevents fugitive emissions. The valve has an energy-efficient 11 watt coil. Positive valve closure occurs in the event of an electrical failure. The molded coil and DIN connector meet NEMA 4X standards. Features the patented Fail-Dry design, which provides advance visual warning of a primary seal malfunction, while allowing the valve to continue in full operation.
