These valves influence the flow rate. A flow control valve allows a variation of the cross-section through which the compressed air flows. A non-return function is provided in parallel with the throttle point, which means that the compressed air is restricted only in one of the possible directions of the flow of air. While installing the valves, the direction of the non-return function should be observed, normally metering out.

These space saving valves are mounted directly into the cylinder port or valve housing without accessories. They can be turned through 360⁰
