Quick Exhaust Valve 150 psi

The Legris 7982 22 22 is a brass, nickel-plated quick exhaust valve rated for a maximum operating pressure of 150 psi and a minimum of 10 psi. It suits pneumatic systems that need rapid cylinder exhaust to increase cycle speed. The component operates between 0 and 160 degrees Fahrenheit.

Half-inch NPT female ports

Both inlet and outlet use 1/2 inch NPT female threads, allowing direct connection to standard pipe fittings without adapters. The compact body measures 9/16 inch in overall length and 2 13/16 inches in overall height, so it fits in tight plumbing layouts. Brass construction resists corrosion in compressed-air service.

Upgrade from slower exhaust methods

Replacing a standard exhaust port or needle valve with this unit reduces back-pressure and cuts cycle time on single-acting cylinders. The jump is worthwhile when machine timing is limited by exhaust flow rather than supply pressure. Buyers who need adjustable flow control or integrated silencing should look elsewhere.
