Ingersoll Rand Air Compressor Check Valve – 85582112

A 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 properly functioning check valve will prevent 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.

The Ingersoll Rand 85582112 compressor check valve can also be changed out annually as a preventive maintenance item to lengthen the life of the motor and prevent costly air leaks.

This check valve will fit the following piston/reciprocating compressors from Ingersoll Rand:

  • 2475N7.5-P (full/premium package models*)
  • 2545K10-V (value package model – does not have air cooled aftercooler or auto drain)
  • 2545K10-VP (value plus package model – with air cooled aftercooler and auto drain)
  • 2545K10-P (premium package – includes low oil level switch, air cooled aftercooler, and auto drain)

*Premium package compressors on the 2475 compressor were shipped with a low oil level switch, air cooled aftercooler, or automatic tank drain. If your air compressor was purchased without the above three items included, you will instead want to purchase an 85582229.

85582229 is an OEM check valve by Ingersoll Rand. If you are unsure of what check valve will fit your Ingersoll Rand compressor, please contact our parts department at 1-866-204-9599
