Versa 316 Stainless Steel Quick Exhaust Valves, 1/4" NPTF Port Size

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" - which is a soft-material seal - 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.
