Ingersoll Rand 32141558 OEM Piston Air Compressor Check Valve
An air compressor check valve is a one way valve designed to let the compressed air go from the compressor pump into the tank. Check valves allow the air to flow in one direction only, preventing backflow from the tank to the pump. A well functioning check valve prevents the compressor from having to start against backpressure, which can otherwise damage the motor and cause strain on the pump.
If air is leaking out of the pressure switch when the compressor is off, the check valve typically needs to be changed out. This results in debris or dirt causing the valve to stay open, letting air from the tank back through the small copper unloader line that connects to the pressure switch. If air leaks from the pressure switch when the compressor is shut off, you should replace the check valve rather than the pressure switch.
32141558 is an OEM check valve for piston compressors manufactured by Ingersoll Rand. This valve was used on several discontinued reciprocating compressors. Please contact us to ensure this is the proper part for your air compressor.
