The Ingersoll Rand 47642702001 37952389 Thermostatic Valve Kit combines an extended preventive-maintenance reference with a dedicated thermal-control component for compatible rotary screw compressor systems. 47642702001 is identified as an 8,000-hour water-cooled preventive maintenance kit for older Cobra M132-160 compressors, while 37952389 is catalogued as a thermostatic valve kit for Ingersoll Rand compressor applications.
Temperature control is essential to the lubrication system of an oil-injected screw compressor. Compressor lubricant must perform several functions simultaneously, including lubrication, cooling, sealing, and protection against contamination and moisture-related issues. The thermostatic valve helps keep the lubricant within the appropriate operating range by controlling its path through the oil-cooling circuit.
When lubricant temperature is low, the valve can bypass the oil cooler in applicable designs, allowing the oil to warm more quickly. As operating conditions change, the thermal-control system regulates oil flow to support more stable temperature management.
A malfunctioning thermostatic valve can disrupt this balance. A valve that remains open or closed incorrectly may contribute to abnormal oil temperatures, inefficient cooling behavior, or unstable compressor operation. Replacing the correct service component can therefore be an important part of restoring the intended lubrication-system performance.
The relationship between 47642702001 and 37952389 should be interpreted as a maintenance-reference pairing rather than proof that 37952389 is included in every 47642702001 package. The package number identifies the scheduled maintenance kit, while 37952389 identifies the individual thermostatic valve component. The machine-specific bill of materials should be checked before assuming package contents.
For maintenance and purchasing teams, accurate identification of the thermostatic valve helps reduce installation errors and supports consistent compressor service. Before ordering, verify the compressor model, serial number, valve configuration, temperature characteristics, and current Ingersoll Rand documentation.

Where It Excels in Industrial Use
8,000-Hour Water-Cooled Maintenance: 47642702001 is identified as an 8,000-hour water-cooled preventive maintenance kit for older Cobra M132-160 screw compressors.
Oil Temperature Control: 37952389 is identified as an Ingersoll Rand thermostatic valve kit used to regulate lubricant temperature in compatible rotary screw compressors.
Cold-Start Protection: The thermostatic valve helps control oil flow during low-temperature conditions, allowing the lubricant to reach an appropriate operating temperature more efficiently.
Lubrication-System Stability: Proper temperature regulation helps maintain the lubricant within its intended operating range and supports stable compressor operation.
Scheduled Thermal-System Service: The valve kit is suitable for planned maintenance where the applicable compressor documentation specifies 37952389.
Key Strengths at a Glance
Dedicated Thermostatic Valve Reference: 37952389 is catalogued as a thermostatic valve kit and thermal valve assembly for Ingersoll Rand compressor applications.
Automatic Oil-Flow Regulation: The thermostatic valve controls oil routing according to temperature, including bypassing the oil cooler when the lubricant is cold in applicable systems.
Compressor-Specific Service: Correct valve selection helps maintain the designed thermal balance of the lubrication circuit.
Maintenance-Focused Design: A dedicated valve kit provides a service solution without automatically requiring replacement of the complete cooling or lubrication assembly.
Configuration-Specific Fitment: Thermostatic valve specifications can differ between compressor configurations, so model, serial number, and current parts documentation should be checked before installation.
Technical FAQs
1. What is Ingersoll Rand 37952389?
37952389 is identified as an Ingersoll Rand thermostatic valve kit or thermal valve assembly for compatible compressor applications.
2. What is 47642702001?
47642702001 is identified as an 8,000-hour water-cooled preventive maintenance kit for older Cobra M132-160 screw compressors.
3. What is the relationship between 47642702001 and 37952389?
47642702001 identifies the preventive-maintenance package, while 37952389 identifies an individual thermostatic valve kit. The exact contents of the maintenance package should be confirmed against the compressor-specific bill of materials.
4. What does a thermostatic valve do in an oil-injected screw compressor?
The valve regulates lubricant flow according to oil temperature, directing oil through or around the cooler as required to help maintain the intended operating temperature.
5. Why is compressor oil temperature important?
Proper lubricant temperature supports effective lubrication, cooling, sealing, and moisture control. Operating with unsuitable oil temperature can affect compressor performance and component protection.
6. What happens when the oil is cold?
In applicable systems, the thermostatic valve can bypass the oil cooler so that the lubricant warms more rapidly rather than being unnecessarily cooled during low-temperature operation.
7. Can 37952389 be used on every Ingersoll Rand compressor?
No. Thermostatic valve configurations vary across compressor models. The compressor model, serial number, valve configuration, and current parts documentation should be verified before installation.
8. What symptoms can indicate a thermostatic valve problem?
Abnormally high or low oil temperature, unstable temperature behavior, or improper oil-cooler flow can indicate a problem with the thermal-control system. Diagnosis should also consider the oil cooler, temperature sensor, oil condition, and related components.
9. Can 37952389 be replaced by another thermostatic valve with similar dimensions?
Not automatically. Opening characteristics, temperature rating, flow behavior, physical configuration, sealing, and compressor application must all be compatible.
10. Is 37952389 interchangeable with 37952397?
Both numbers are catalogued as Ingersoll Rand thermostatic-valve references, but they should not be assumed interchangeable. Separate catalogue entries identify 37952389 and 37952397 as distinct valve references, and application-specific verification is required.
