1. QC are flow control valves with pressure compensators: The controlled flow rate is independent of pressure va- riations.
2. They can be equipped GQ overlap boards with the mo- dular check adjusting speed valve.
3. They are usually supplied with a built- in check valve to allow the free flow in the opposite direction.
4. The flow is regulated by turning a graduate micrometer knob, clockwise rotation increases the throttling.
