Precisely control and regulate air flow with our compact functional fittings. Throttle check fittings enable speed control of pneumatic cylinders – optionally via exhaust or supply air throttling. Throttle silencers in exhaust ports also allow adjustment of actuation speed. Check fittings permit air flow in one direction only, while unlockable check fittings can be switched via pneumatic signal as needed. Our quick exhaust fittings increase the actuation speed of pneumatic cylinders.
