Ingersoll Rand Pilot Unloader Check Valve - 49816283

The unloader check valve prevents back flow as the compressor builds pressure. The pilot remains closed until the downstream pressure reaches the unload setting. The pilot then opens and pressurizes the unloader valve. This causes the unloader valve to open and vent the excess air from the compressor to the atmosphere. As the compressed air downstream is used and the pressure drops to the load setting the pilot closes and depressurizes the unloader valve. The unloader valve then closes and the pressure begins to build again and repeats the cycle.

This valve has a 5/8" flare inlet on the top where the discharge line from the compressor pump connects to. The bottom port is 1/2" NPT and threads into the stem from the compressor tank. The safety valve is included and there is also a 1/8" port to connect the throttle control/slowdown cable back to the Honda or Kohler engine. This valve is pre-set to operate between 145-175psi.

The 49816283 fits Ingersoll Rand's newer truck mount style 2475 gas air compressors that include the 14hp Kohler CommandPro and 13hp Honda GX390 engines.
