ST128400AV - ST128400AV  Combo Check Valve, Pilot Unloader Valve
Description:

Campbell Hausfeld load genie check valve.  This valve is a combo check valve and pilot unloader valve.  This valve is used on units that are continously running air compressors (many Campbell Hausfeld truck mount air compressors and larger Campbell Hausfeld stationary gas air compressors.Click Here to find a replacement pilot unloader valve

These valves attach to the pressure switch and bleed off or "unload" excess air in the lines and off of your pump head so your air compressor can easily start up. This is especially necessary after the unit reaches its max pressure and shuts off; the schrader valve is tripped by a lever on the pressure switch, which opens the valve and bleeds the air from the unloader tube and discharge tube. If air leaks from this valve constantly after the units shuts off, replace your check valve, not the unloader valve.
