PQ-FV in-line flow controls use a tube-to-tube connection that can be installed as a meter-in or meter-out device. The PQ-C elbow controls are for lightweight applications when mounting directly to an NPT port on a cylinder or valve is required.
Intake air in meter-out versions flows freely through the flow control; exhaust air is metered out through an adjustment screw. With the meter-in style, air is metered in through an adjustment screw; exhaust air flows freely. Control is varied through a finely threaded adjustment screw. A locking nut is provided so it can be secured in its final setting.
The controls are available in 25 different models: #10-32, 1/8, 1/4, and 3/8-in. NPT.
