The Ingersoll Rand 47704439001 / 47690563001 Thermal Valve Rebuild Kit is a maintenance component intended for servicing the thermal-control valve used on compatible rotary screw compressors.
In an oil-flooded compressor, lubricant serves several functions at the same time. It provides lubrication, assists rotor sealing, and carries heat away from the compression process. Because lubricant temperature has a direct influence on these functions, the thermal valve plays an important role in directing oil through the cooling circuit as operating conditions change.
The 47690563001 is specifically identified as a Kit, Thermal Valve 180–198F, Rebuild, with application information linking it to the RS45–75I/N compressor range. The available parts description also identifies it as a rebuild kit rather than a complete replacement valve.
For maintenance teams, using the correct thermal-valve rebuild kit can provide a targeted way to restore valve function during planned service. Before installation, the existing valve should be inspected carefully and the replacement components installed according to the applicable Ingersoll Rand maintenance procedure.

Ingersoll Rand Service Thermal Valve Kit
Where It Excels in Industrial Use
Thermal Regulation Service: The 47690563001 is a thermal valve rebuild kit designed to restore the service condition of the compressor's thermal-control valve assembly.
RS45–75I/N Compressor Platforms: Available parts information identifies this kit for RS45–75I/N compressors and specifies a 180–198°F thermal-valve range.
Lubricant Temperature Management: The thermal valve regulates lubricant flow through the cooling circuit, helping the compressor maintain an appropriate operating temperature.
Scheduled Compressor Overhaul: A rebuild kit is useful when the existing thermal-valve assembly remains serviceable but its internal wear components require renewal.
Key Strengths at a Glance
Defined Temperature Range: The kit is specified for a 180–198°F thermal-valve operating range.
Rebuild-Oriented Design: Rather than automatically replacing the complete valve assembly, the kit provides components intended for thermal-valve refurbishment.
RS45–75I/N Compatibility: Its documented application makes it particularly relevant to maintenance programs supporting these compressor platforms.
OEM Maintenance Reference: The 47690563001 is listed as an Ingersoll Rand thermal-valve rebuild kit, supporting part-number-based maintenance planning.
Technical FAQs
1. What is Ingersoll Rand 47704439001 / 47690563001?
It is a thermal valve rebuild kit for compatible Ingersoll Rand rotary screw compressors. The listed specification identifies the kit as a 180–198°F thermal-valve rebuild.
2. What is the function of the thermal valve?
The thermal valve controls lubricant routing through the compressor cooling circuit according to lubricant temperature, helping maintain the intended operating-temperature range.
3. What temperature range is specified for 47690563001?
The kit is identified as 180–198°F.
4. Which compressors are associated with 47690563001?
Trade and parts information identifies the rebuild kit for RS45–75I/N compressor applications. Final fitment should be checked against the compressor model and serial number.
5. Why is thermal-valve operation important in an oil-flooded screw compressor?
Lubricant temperature affects cooling, viscosity, sealing, and overall compressor operation. Proper thermal regulation helps keep the lubricant within its intended operating range.
6. What can happen if the thermal valve sticks or operates incorrectly?
Incorrect valve operation can contribute to abnormal lubricant temperature, unstable cooling performance, or inefficient oil-circuit operation. The cooler, thermostat, sensors, and lubricant condition should also be checked during diagnosis.
7. Is 47690563001 a complete thermal-valve assembly?
No. It is specifically identified as a rebuild kit. The existing valve assembly must be suitable for rebuilding, and the applicable service procedure should determine which components are replaced.
8. Can the thermal valve affect compressor operating efficiency?
Yes. Improper lubricant-temperature control can affect the compressor's cooling and lubrication conditions. Maintaining the thermal-control system in good working order supports stable operation.
9. What should be inspected when rebuilding the thermal valve?
The valve body, sealing surfaces, internal moving components, springs or thermostatic components, and related seals should be inspected for wear, contamination, corrosion, or damage before reassembly.
10. What should be verified before ordering 47704439001 / 47690563001?
Verify the compressor model, serial number, existing thermal-valve part number, required temperature range, and applicable service documentation. Ingersoll Rand's Parts Finder is designed to identify OEM parts by equipment type and compressor model.
