Product Overview
The Ingersoll Rand 47704430001 47690563001 Temperature Control Valve Repair Kit is a maintenance component intended for servicing the temperature control valve assembly in compatible Ingersoll Rand industrial compressor systems.
Temperature control is an important part of compressor operation. During normal operation, the control valve helps regulate the temperature of the circulating lubricant or oil by controlling the flow path through the cooling system. Maintaining the correct operating temperature helps support lubrication performance, reduce thermal stress, and maintain stable compressor operation.
The repair kit is used when the temperature control valve requires maintenance rather than complete replacement. Depending on the condition of the original assembly, replacing worn sealing elements or internal components can restore proper valve operation and help prevent temperature-related compressor faults.

Function and Working Principle
The temperature control valve is part of the compressor’s thermal-management system.
A simplified arrangement is:
Compressor
↓
Lubricating Oil Circuit
↓
Temperature Control Valve
↙ ↘
Oil Cooler Bypass Path
↓
Compressor Lubrication System
The valve responds to lubricant temperature and controls the flow path so that the compressor can maintain an appropriate operating temperature.
When the oil is relatively cold, the valve may direct a greater proportion of flow through a bypass path, allowing the system to reach operating temperature more efficiently.
As the oil temperature increases, the valve progressively directs more flow toward the cooler.
This process can be represented conceptually as:
Low Oil Temperature
→ More Bypass
→ Faster Warm-Up
Higher Oil Temperature
→ More Cooling Flow
→ Temperature Regulation
The repair kit is used to restore the mechanical components responsible for this regulating function.
Role in Compressor Systems
Temperature control is critical in lubricated compressors because oil performs several important functions:
- Lubrication
- Heat transfer
- Bearing protection
- Sealing
- Internal component cooling
If the oil becomes excessively hot, lubrication performance can deteriorate and thermal stress may increase.
If the oil remains excessively cold, moisture and condensation-related problems may become more likely, while the lubricant may not reach its intended operating characteristics.
The temperature control valve therefore contributes to maintaining the compressor within its intended thermal operating range.
Typical Applications
The 47690563001 repair kit may be used during maintenance of compatible compressor temperature-control valve assemblies.
Typical maintenance situations include:
- Valve leakage
- Incorrect operating temperature
- Valve sticking
- Damaged sealing elements
- Internal valve wear
- Poor temperature regulation
- Preventive compressor overhaul
The exact compressor models and valve assemblies compatible with a particular repair kit should always be confirmed before ordering or installation.
Installation Guide
1. Confirm the Replacement Part
Before starting maintenance, verify:
Ingersoll Rand 47704430001
47690563001 Temperature Control Valve Repair Kit
Compare the replacement kit with the existing valve assembly.
Check:
- Part number
- Component arrangement
- Sealing components
- Valve components
- Physical dimensions
- Existing valve configuration
Do not begin disassembly until the replacement components have been identified.
2. Shut Down the Compressor
Stop the compressor using the normal shutdown procedure.
Then isolate the machine from its energy sources according to the site’s lockout/tagout procedure.
The system should be:
- Shut down
- Electrically isolated
- Depressurized
- Allowed to cool
- Secured against accidental restart
Do not work on a hot or pressurized oil circuit.
3. Allow the System to Cool
The temperature control valve is associated with the compressor’s lubrication and cooling circuit.
Hot lubricant can cause serious burns.
Allow sufficient time for:
- Oil temperature to decrease

Lubricate seals only with a lubricant approved for the compressor system and compatible with the sealing material.
10. Reassemble the Valve
Reassemble the valve carefully.
Ensure that:
- Moving components operate smoothly
- Seals are seated correctly
- No seal is pinched
- Retaining components are installed
- Valve components are correctly aligned
If torque specifications are provided for the specific valve assembly, use the specified values rather than estimating tightening force.
11. Reinstall the Valve

Initial Inspection
Check for:
- Oil leakage
- Abnormal noise
- Vibration
- Loose fittings
- Temperature abnormalities
Temperature Monitoring
Observe the compressor’s oil temperature as it moves from startup toward normal operation.
The temperature should increase and stabilize in a controlled manner rather than remaining excessively low or rising uncontrollably.
Leakage Inspection
Inspect the repaired valve and surrounding connections.
Even a small oil leak should be investigated because oil loss can affect compressor lubrication.
Functional Verification
Confirm that:
- The compressor reaches normal operating temperature.
- Temperature remains stable.
- No temperature-related alarms occur.
- Oil circulation is normal.
- No abnormal leakage is present.
Troubleshooting Guide
Problem 1: Compressor Oil Temperature Is Too High
Possible causes include:
- Temperature control valve stuck
- Valve not regulating correctly
- Cooler airflow problem
- Oil cooler contamination
- Incorrect oil level
- High ambient temperature
- Restricted cooling circuit
Recommended Checks

With supplied dimensions of 100 × 15 × 80 mm and a weight of 0.15 kg, it is convenient for compressor maintenance inventory and planned service operations.
The temperature control valve plays an important role in compressor thermal management by regulating lubricant flow through the cooling circuit. Proper valve operation helps maintain suitable oil temperature and supports reliable lubrication of internal compressor components.
Successful installation requires more than simply replacing the old components. The compressor must be safely isolated and cooled, the valve must be cleaned and inspected, replacement components must be installed in the correct orientation, and all seals and connections must be properly positioned.
After repair, commissioning should include careful monitoring of operating temperature, oil leakage, valve behavior, and overall compressor performance. If the temperature remains abnormal after valve servicing, technicians should investigate the oil cooler, airflow, oil level, temperature sensor, and other parts of the thermal-management system rather than assuming that the repair kit itself has failed.
