According to Clippard, its PQ-FV in-line flow controls integrate easily with existing circuitry and are lightweight and compact in size. Since it is a tube-to-tube connection, in-line flow controls are installable as either a meter-in or meter-out device. For meter-out versions, intake air flows freely through the flow control and exhaust air meters out through an adjustment screw. With the meter-in series, air meters in through an adjustment screw and exhaust air flows freely. Control is variable via an adjustment screw. A locking nut is also on board.
