Introduction

The Ingersoll Rand 47690462001 / 95028502 MPCV Rebuild Kit is a service-oriented product listing for maintaining the minimum pressure check valve and its associated sealing interface on compatible rotary screw compressors.

The primary reference 47690462001 is documented as an MPCV Rebuild Kit, with parts information identifying the application as RS45–75I/N. The associated 95028502 is a Standard 232 O-ring used in the R55–75 compressor family. The Ingersoll Rand R55–75 parts documentation specifies it with a 2.734-inch inside diameter and 0.139-inch cross-section.

The minimum pressure check valve is an important component in an oil-injected rotary screw compressor. It helps maintain internal pressure needed for proper oil circulation and separator performance while allowing compressed air to move into the discharge system under the appropriate operating conditions.

During service, deterioration of valve internals or sealing components can affect pressure stability and increase the possibility of leakage. A properly selected rebuild kit allows technicians to renew serviceable components while retaining the existing valve body when it remains within acceptable condition.

The two supplied references are treated as one product listing as requested. Final compatibility should be confirmed against the compressor model, serial number, and current OEM parts list.
