Product Overview
The Ingersoll Rand 47572176001 47552954001 Service Kit Thermostatic Valve is a maintenance kit for the temperature control valve used in compatible rotary screw air compressors. The part reference 47552954001 is listed as a temperature control valve maintenance kit for Ingersoll Rand R90–160 compressor applications. Its purpose is to support servicing of the valve assembly that regulates lubricant temperature within the compressor’s cooling and lubrication circuit.
In an oil-injected screw compressor, temperature control is closely connected to lubrication performance. The compressor oil absorbs heat during compression and must circulate through the appropriate cooling path to maintain suitable operating conditions. The thermostatic valve regulates oil flow according to temperature, directing the lubricant through the cooler when cooling is required and managing the flow path as the oil warms up.
A malfunctioning valve can interfere with this process. If the valve does not move correctly or fails to regulate the oil flow, the compressor may experience prolonged warm-up, excessive operating temperature, or unstable temperature behavior. A service kit allows the applicable valve assembly to be maintained when the fault originates from serviceable internal components.
During scheduled maintenance, technicians may inspect the temperature control valve alongside the oil filter, oil cooler, and associated piping. Servicing the valve can help restore its intended operation when wear or deterioration of its internal parts is responsible for the problem. However, a faulty temperature reading or overheating condition does not automatically mean the valve is defective; restricted oil flow, cooler fouling, and other system faults can produce similar symptoms.
The 47552954001 reference is associated with the R90–160 compressor range in parts listings. The service kit should be understood as a valve-maintenance component rather than a complete compressor overhaul package. Its function is specific to the temperature control assembly and should not be confused with a minimum pressure valve repair kit or a general-purpose lubricant.

Working Principle
The thermostatic valve regulates the route taken by compressor oil according to its temperature. Oil leaving the compression and separation stages carries heat generated during operation. The temperature control valve manages the flow path so the oil can reach the appropriate operating temperature and pass through the cooler when required.
Compressor Air End → Oil Separation Circuit → Thermostatic Valve → Oil Cooler or Bypass Path → Oil Filter → Compressor Air End
When the compressor starts from a relatively cool condition, the valve regulates oil flow to support the required warm-up behavior. As the oil temperature rises, the thermostatic element responds to the changing temperature and adjusts the valve position. Depending on the valve design and operating condition, this changes the proportion of oil passing through the cooler versus the bypass path.
Once the compressor reaches its normal operating range, the valve continues to regulate the oil circuit according to the temperature response of its internal mechanism. This helps maintain suitable lubrication conditions and prevents the cooling circuit from operating as though maximum cooling were always required.
The service kit is intended to support maintenance of the applicable valve assembly. During servicing, internal components and sealing surfaces may be inspected for wear, sticking, contamination, or deterioration. The exact repair procedure depends on the installed valve design and the components supplied in the kit.
A valve that sticks in an incorrect position can alter the oil temperature response. If oil bypasses the cooler when additional cooling is required, the compressor may run too hot. If the valve restricts the intended bypass path during warm-up, the oil may take longer to reach its normal operating condition. Correct diagnosis should distinguish valve problems from cooler restrictions, oil filter blockage, incorrect oil level, and inaccurate temperature measurements.
Role in an Ingersoll Rand Compressor System
The thermostatic valve service kit belongs to the compressor’s oil temperature control system. The valve assembly regulates oil routing, while the cooler removes heat from the lubricant and the filter removes contaminants before the oil returns to the lubrication circuit.

Technical FAQs
What does the thermostatic valve do in an oil-injected screw compressor?
It regulates the route taken by circulating oil according to temperature, controlling the flow through the oil cooler and bypass path. This helps the compressor maintain suitable oil operating conditions during warm-up and normal operation.
Can a faulty thermostatic valve cause compressor overheating?
Yes. If the valve does not direct sufficient oil through the cooler when cooling is needed, oil temperature may rise. Cooler restrictions, oil flow problems, and other faults can cause similar symptoms and should also be considered during troubleshooting.
Is the 47552954001 kit a complete thermostatic valve assembly?
The part is identified as a temperature control valve maintenance kit rather than a complete compressor assembly. It is intended for servicing the applicable valve; the existing housing and other reusable parts must remain suitable for repair.
Why might a compressor take unusually long to reach its normal oil temperature?
Possible causes include a thermostatic valve that does not regulate the bypass path correctly, low ambient temperature, operating conditions, or a temperature measurement problem. The valve response and oil circuit should be assessed together to identify the cause.
