A Quick Exhaust 3/2 valve, with an extra large exhaust orifice, is designed to fit directly onto the cylinder port connection. The purpose of a Quick Exhaust Valve is to evacuate cylinder air directly to the atmosphere, increasing reaction time of the cylinder rod or valve actuator.
A quick Exhaust Valve is a three-ported valve with one inlet port, one cylinder port and a larger exhaust port.
When the inlet port is pressurized, the exhaust port is closed by the “Flapper” (“Shuttle” on QE-6-316) and the inlet port is connected to the cylinder port.
When pressure falls at the inlet of the Quick Exhaust Valve the cylinder port is automatically opened to the exhaust and the cylinder is rapidly depressurized.
