Clippard’s PQ-FV In-Line Flow Controls are designed to be easily added to existing circuitry and are lightweight and compact in size. Since it is a tube-to-tube connection, in-line flow controls may be installed as a meter-in or meter-out device. The PQ-C Elbow Controls are a good fit for low cost and lightweight applications when mounting directly to an NPT port on a cylinder or valve is required. In the meter-out versions, intake air flows freely through the flow control; exhaust air is metered out through an adjustment screw. With the meter-in series, air is metered in through an adjustment screw; exhaust air flows freely.
