Introduction
The Ingersoll Rand 47704436001 / 47690563001 Thermal Valve Rebuild Kit is a specialized maintenance solution for the thermal valve system used on compatible rotary screw compressors.
Temperature management is fundamental to an oil-flooded compressor. Lubricant must perform several jobs simultaneously: it lubricates the airend, removes heat generated during compression, and contributes to sealing between the rotating elements. The thermal valve helps regulate lubricant circulation so that the system can operate within its intended temperature range.
The 47690563001 is identified as a Thermal Valve 180–198°F Rebuild Kit and is associated with RS45–75i/N compressor configurations. Available product information identifies the kit as a seven-piece configuration.
For maintenance teams, rebuilding the existing thermal valve can be an efficient approach when the main valve assembly remains in good condition. Instead of replacing a complete assembly unnecessarily, the service kit focuses maintenance on the components responsible for the valve's mechanical and thermal response.

Technical FAQs
1. What is the primary function of Ingersoll Rand 47704436001 / 47690563001?
It is a thermal valve rebuild kit designed to service the thermal valve assembly in compatible Ingersoll Rand rotary screw compressors. The 47690563001 is identified as a thermal valve 180–198°F rebuild kit.
2. What does the 180–198°F specification represent?
It identifies the thermal operating range associated with this valve configuration. The temperature-responsive valve regulates lubricant flow according to operating temperature.
3. Why is thermal-valve operation important in an oil-flooded screw compressor?
Compressor lubricant provides cooling, sealing, and lubrication. Maintaining the lubricant within its intended operating range helps support proper viscosity, heat transfer, and airend protection.
4. Which compressor configurations are associated with 47690563001?
Available parts information identifies the kit for RS45–75i/N configurations. Exact application should be confirmed against the compressor model and serial number before installation.
5. What happens if the thermal valve remains open or closed incorrectly?
Incorrect valve operation can disturb lubricant temperature control. Depending on the failure mode, the compressor may experience insufficient cooling, excessive lubricant temperature, or abnormal warm-up behavior.
6. Can a thermal valve rebuild kit replace the complete valve assembly?
No. The kit is intended to replace serviceable internal components. If the valve body, seating surfaces, or other major components are damaged, complete valve replacement may be necessary.
7. What symptoms can indicate thermal-valve deterioration?
Abnormal lubricant temperature, prolonged warm-up, excessive operating temperature, temperature fluctuations, or temperature-related compressor alarms can indicate a thermal-control problem. Other cooling-system components should also be checked during diagnosis.
8. How does the thermal valve interact with the compressor cooler?
The thermal valve controls lubricant routing according to temperature, helping determine when lubricant is directed through the cooling circuit. This allows the compressor to reach and maintain an appropriate operating temperature.
9. What should be inspected before rebuilding the thermal valve?
Inspect the valve body, seating surfaces, moving components, springs, seals, and passages for wear, contamination, corrosion, or physical damage. The existing assembly should be suitable for rebuilding before the kit is installed.
10. What should be verified before ordering 47704436001 / 47690563001?
Verify the compressor model, serial number, thermal-valve configuration, temperature specification, and existing part number. The RS45–75i/N application should be treated as configuration-specific rather than universal.
