Parker 0R Quick Exhaust Valves provide rapid exhaust of control air allowing for increased cylinder speed to be accomplished while improving efficiency. When a cylinder can quickly exhaust pressure, cylinder stroke speed will be reduced. The 0R quick exhaust valve has a greater exhaust capacity than the many four-way directional control valves, so increased cylinder speed can be accomplished with a smaller and less expensive control valve. Diaphragm materials are available in Urethane, Nitrile, Fluorocarbon, and PTFE to meet a wide variety of temperature and pressure operating conditions. 0R Quick Exhaust Valves can also be used as shuttle valves, which determine a single pneumatic output from two separate inputs. If pressure is applied to both ports simultaneously, the valve will select the port with the higher pressure.
