Introduction
The Ingersoll Rand 47588564001 / 23392368 Minimum Pressure Valve Service Kit combines a scheduled preventive-maintenance reference with a specialized service kit for the compressor minimum-pressure valve.
47588564001 is cataloged as an 8,000-hour preventive maintenance kit for air-cooled compressors and belongs to Ingersoll Rand's broader scheduled-maintenance product family. Other references in the same family cover 2,000-hour, 4,000-hour, and water-cooled 8,000-hour maintenance intervals.
The independently documented 23392368 is a service MPCV kit. Ingersoll Rand parts records describe it as KIT, SERVICE MPCV DN64, while a later maintenance reference specifies DN51 OUT & DN64 IN.
The minimum-pressure check valve is an important component in a lubricated rotary screw compressor. It helps maintain the minimum pressure required inside the separator system and regulates the flow of compressed air leaving the compressor package.
Maintaining adequate internal pressure is important because the separator system relies on suitable pressure and flow conditions to separate entrained compressor oil from the compressed-air stream. A malfunctioning minimum-pressure valve can therefore affect both pressure control and oil-separation performance.
The valve also acts as a check valve, helping control flow behavior when compressor operating conditions change. Its mechanical condition, sealing surfaces, and regulating components can therefore influence compressor stability.
23392368 is specifically associated with R55I and R75I compressor parts listings. A dedicated RM55-75N/NE parts manual also lists 23392368 as an MPCV service kit, indicating that the reference has been used across multiple compatible R-series configurations.
Because different compressor generations can use different valve configurations, the part number should not be selected solely according to nominal compressor horsepower. The valve connection arrangement, including the documented DN51/DN64 configuration, should also be checked.
During service, technicians should inspect the valve body and mating surfaces for contamination or damage. Internal regulating components should move correctly, and sealing components should be renewed when required by the applicable service procedure.
A properly functioning minimum-pressure valve helps maintain stable separator pressure and controlled compressed-air discharge. This contributes to reliable compressor operation and supports the intended oil-separation process.
The complete physical dimensions and weight of 23392368 could not be reliably verified from the available technical documentation. Because it is a multi-component service kit rather than a single standardized valve body, kit-level dimensions and weight should be confirmed from the actual supplied package.
The supplied pair is treated as one product listing as requested. Public records independently establish 47588564001 as the 8,000-hour air-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 47588564001.
