Introduction
The Ingersoll Rand 47588563001 / 23392368 Minimum Pressure Valve Service Kit combines an 8,000-hour preventive-maintenance reference with a specific valve-service component.
47588563001 is cataloged as an 8,000-hour preventive maintenance kit for water-cooled compressors. It belongs to the same maintenance family as the 2,000-hour, 4,000-hour, and air-cooled 8,000-hour kit references.
The independently documented 23392368 has a substantially different technical role. Parts suppliers identify it as “KIT, SERVICE MPCV DN64”, while other Ingersoll Rand parts listings describe it as a minimum pressure valve service kit.
The minimum pressure valve is an important part of a lubricated rotary screw compressor's pressure-management system. It helps maintain the pressure required in the separator vessel and controls the movement of compressed air from the internal separator system toward the discharge side.
Maintaining the correct minimum pressure is important because the compressor's lubricant and compressed-air separation processes depend on the intended operating pressure conditions. A malfunctioning valve can therefore affect overall compressor behavior even though the valve itself is relatively small compared with the complete compressor package.
The DN64 designation is an important identification characteristic for 23392368. It indicates the nominal valve size associated with the service-kit application and helps distinguish this kit from service kits intended for other valve configurations.
Available parts information specifically associates 23392368 with the R55i platform. Another Ingersoll Rand parts listing identifies the same reference as KIT MPCV SERVICE R55I-14 HAT P, further supporting its relationship with R55i equipment.
The service-kit approach allows technicians to renew the serviceable components of the MPCV without necessarily replacing the complete valve assembly. This can be useful when the valve body remains serviceable but internal sealing or wear components require replacement.
Before service, the valve assembly should be inspected for contamination, scoring, corrosion, damaged sealing surfaces, and abnormal wear. The separator system should also be depressurized according to the applicable service procedure before the valve is removed.
23392368 should not be confused with the Ingersoll Rand 22067177 inlet-valve repair kit, which services a different valve function. The 22067177 reference is an inlet/unloader valve repair kit used on smaller UP6 rotary screw compressors.
Likewise, 23392368 is not an air filter, oil filter, or separator element. Ingersoll Rand parts listings separately identify components such as 23424922 as coolant-filter elements and 23429798 as high-dust air-filter elements.
The supplied pair is treated as one product listing as requested. Public records independently identify 47588563001 as an 8,000-hour water-cooled preventive-maintenance kit and 23392368 as an MPCV/minimum-pressure-valve service kit. The available documentation does not independently establish that 23392368 is the complete bill of materials contained in 47588563001.
