Product Overview
The Ingersoll Rand 47690563001 Temperature Control Valve Repair Kit is a maintenance component designed for compatible oil-injected rotary screw air compressor systems. Associated with the Ingersoll Rand 47704432001 service kit, it is used to restore the operating condition of the compressor’s temperature control valve and maintain appropriate lubricant temperature during normal operation.
Temperature management is essential in an oil-injected screw compressor because the lubricant performs several functions simultaneously. It provides lubrication, removes heat from the compression process, assists with sealing between rotating components, and carries heat toward the compressor cooling system. If the lubricant temperature becomes too low or too high, compressor efficiency, lubrication quality, condensation control, and component life can be affected.
The temperature control valve regulates the flow path of compressor lubricant according to operating temperature. The 47690563001 repair kit provides replacement service components for the valve assembly, helping restore proper temperature-control performance without necessarily replacing the complete valve assembly.
The supplied dimensions are 100 × 15 × 80 mm, with a specified weight of approximately 0.15 kg.

Function and Working Principle
The temperature control valve manages the flow of lubricant between the compressor’s cooling circuit and the compressor lubrication circuit.
A simplified system can be represented as:
Compressor Air End
↓
Hot Compressor Lubricant
↓
Temperature Control Valve
↙ ↘
Oil Cooler Bypass Flow
↘ ↙
Controlled-Temperature Lubricant
↓
Compressor Air End
When lubricant temperature is relatively low, the valve can direct lubricant through an appropriate bypass path to help the compressor reach its normal operating temperature.
As lubricant temperature increases, the valve progressively directs more lubricant through the oil cooler. This allows excessive heat to be removed before the lubricant returns to the compressor.
The exact valve behavior depends on the compressor design and applicable control characteristics.
Why Temperature Control Is Important
Correct lubricant temperature contributes to:
- Proper lubrication
- Efficient heat removal
- Stable compression
- Reduced condensation risk
- Improved oil separation
- Reduced component wear
- Stable compressor operation
- Longer lubricant service life
A temperature control valve that sticks or responds incorrectly can therefore create several apparently unrelated compressor problems.

Installation and Repair Guide
1. Verify the Repair Kit
Before beginning maintenance, confirm:
Part Number: 47690563001
Associated Service Kit: 47704432001
The repair kit should only be used with a compatible temperature control valve assembly.
2. Shut Down the Compressor
Before servicing the temperature control valve:
- Stop the compressor.
- Disconnect electrical power.
- Isolate the compressor.
- Release system pressure.
- Allow the lubricant and components to cool.
- Apply appropriate lockout/tagout procedures.
Hot compressor oil can cause serious burns.
3. Allow the Lubricant to Cool
The temperature control valve is directly associated with the compressor lubricant circuit.
Do not open the circuit while the oil remains at an unsafe temperature.
4. Locate the Temperature Control Valve
Identify the valve within the compressor lubricant circuit.
Inspect surrounding:
- Oil lines
- Fittings
- Cooler connections
- Valve housing
- Sealing surfaces
5. Remove the Valve Assembly
Follow the applicable compressor service procedure.
Carefully disconnect the valve without damaging:
- Oil pipes
- Threads
- Housing surfaces
- Connections
- Adjacent components
6. Inspect the Existing Valve
Before installing repair components, inspect for:
- Valve sticking
- Contamination
- Wear
- Corrosion
- Damaged sealing surfaces
- Abnormal oil deposits
Determine whether the valve body itself remains suitable for reuse.
7. Disassemble the Valve
Disassemble the valve carefully and keep components organized.
Pay particular attention to:
- Component orientation
- Spring position
- Sealing elements
- Valve movement
- Internal contamination
8. Install Repair Kit Components
Install the components supplied with the 47690563001 Temperature Control Valve Repair Kit.
Verify:
- Correct component placement
- Proper seating
- Clean surfaces
- Correct orientation
- Free mechanical movement
Do not force internal components into position.
9. Inspect Sealing Surfaces
Before reassembly, verify that sealing surfaces are:
- Clean
- Smooth
- Free from scratches
- Free from foreign material
Damaged sealing surfaces can cause lubricant leakage.
10. Reassemble the Valve

Ensure all components move correctly before installation.
11. Reinstall the Valve
Install the repaired valve into the compressor lubricant circuit.
Reconnect:
- Oil lines
- Fittings
- Mounting hardware
- Associated components
12. Restore the System
After completing the repair:
- Verify all connections.
- Confirm correct oil level.
- Restore electrical power.
- Start the compressor.
- Allow it to warm up.
- Monitor lubricant temperature.
- Inspect for oil leakage.
- Confirm stable operating conditions.
Commissioning Procedure
After repairing the temperature control valve, monitor the compressor during warm-up.
Initial Startup
Check:
- Oil pressure
- Oil temperature
- Compressor loading
- Abnormal noise

- Cooling-system problems
Inspect valve movement and operating conditions.
Problem 4 — Compressor Runs Hot
Possible causes:
- Valve malfunction
- Restricted oil cooler
- Insufficient cooling airflow
- Low lubricant level
- Incorrect lubricant
The temperature control valve should be inspected as part of the complete thermal-management system.
Problem 5 — Oil Leakage Around Valve
Possible causes:
- Damaged seal
- Improper reassembly
- Scratched sealing surface
- Loose connection
- Incorrect installation
Inspect the repaired valve and all associated connections.
Problem 6 — Valve Sticks
Possible causes:
- Contaminated lubricant
- Foreign particles
- Internal corrosion
- Component wear
- Incorrect assembly
Disassemble and inspect the valve if sticking is confirmed.
Problem 7 — Compressor Temperature Takes Too Long to Stabilize
Possible causes:
- Incorrect valve operation
- Excessive cooling
- Low load condition
- Environmental temperature
- Valve response problem
Check the temperature control system before replacing unrelated components.
Problem 8 — High Lubricant Consumption
Possible causes:
- Excessive operating temperature
- Oil separation problems
- Incorrect oil level
- Oil leakage
- Temperature-control malfunction
Inspect the temperature control valve together with the air-oil separator and oil system.
Diagnostic Workflow
Use a systematic troubleshooting sequence:
Compressor Air End
↓
Hot Lubricant
↓
47690563001 Temperature Control Valve
↓
Oil Cooler / Bypass Circuit
↓
Controlled-Temperature Lubricant
↓
Compressor Air End
↓
Temperature Monitoring
This sequence helps distinguish valve-related problems from cooling-system or lubrication-system faults.

Common Repair Errors
Installing Incorrect Components
Only compatible repair components should be installed in the valve assembly.
Incorrect Component Orientation
Internal valve components must be installed in their proper positions.

Damaged sealing elements can cause oil leakage after repair.
Contaminated Assembly
Dirt or foreign material can cause the repaired valve to stick.
Ignoring the Oil Cooler
A high oil temperature does not necessarily indicate a valve fault. Cooler blockage and inadequate airflow must also be considered.
