The Ingersoll Rand 18983700 Inlet Valve Rebuild Kit is an OEM service kit designed to rebuild the NC (normally closed) inlet valve used on selected Ingersoll Rand rotary screw air compressors. The inlet valve controls the volume of air entering the compressor airend during loading and unloading, making it essential for maintaining proper capacity control, operating pressure, and compressor efficiency.
The 18983700 kit contains the necessary replacement components for rebuilding the inlet valve assembly rather than replacing the complete valve. Renewing worn internal components helps restore smooth valve operation, reliable sealing, and accurate air-intake control. This can help reduce air leakage, improve load/unload response, and maintain dependable compressor performance.
