Blocking Valves control the flow of air or oil in one direction to regulate the speed of the piston in pneumatic applications. The knurled knob can be used to increase or decrease the flow and tightened to maintain the desired setting.
Quick Exhaust Valves are non-return valves that increase piston speeds and can be used as a differential shuttle valve. The compact design uses low operating pressure and allows full flow in one direction.
