Conrader NG Series 3/4" Compression x 1/2" NPT 90 Degree Inlet Air Compressor Pilot/Unloader/Check Valve Combo – 145-175 PSI

This is a U.S.-made NG series combo valve from Conrader, built for use with gas-powered or electric constant-run air compressors. It combines a pilot valve, discharge valve, and check valve in one.

The valve includes a 3/4" compression side inlet for copper tubing, a 1/2" male NPT outlet to the tank connection, and a 1/8" female NPT port on the back for throttle or unloader control. It’s factory set to operate between 145 and 175 PSI and features a built-in manual unloader valve. The unloader exhaust outlet also has a muffler to reduce noise during unload.

Note: The 3/4" compression inlet comes into this valve at a 90 degree angle as shown in the photos.
