This listing is for one new 110-135 PSI piloted discharge check valve/unloader valve combo. This check valve is an NS series valve. This valve is usually used on compressors that pump less than 20 CFM and can be used on gas or electric compressors. This valve is equipped with an in-line check valve and attached to the side is a built-in piloted unloader valve set 110-135 PSI. This valve also has a muffler on the exhaust air port to quiet down the unloaded exhaust air that is released once the compressor reaches 135 PSI. On the side of the valve, it has a 1/8" female NPT port, to control the throttle on a gas engine and/or unloader valves on some pumps.
