The quick exhaust valves are designed to be highly sensitive and exert differential pressure across the diaphragm to open the exhaust. The latest valves are now being design with a lightweight material, which can easily be supported by the piping of the system.These corrosion resistant fittings have an oil resistant diaphragm, and the high quality fittings also ensure quite operations, unlike the usual chattering of the low quality valves. These valves ensure a rapid return and turn volume of the cylinder, and offer multiple porting options for efficient systems.
