Product Overview
The Ingersoll Rand 47704431001 47690563001 Temperature Control Valve Repair Kit is a compressor maintenance component designed to restore the operating condition of the temperature control valve in compatible oil-injected compressed-air systems.
The temperature control valve is an important part of the compressor’s lubrication and cooling circuit. It regulates the path of compressor oil through the cooling system according to operating temperature. By controlling oil flow through the oil cooler, the valve helps maintain an appropriate oil temperature during different compressor operating conditions.
Proper temperature control is important because compressor oil performs several critical functions, including lubrication, sealing, heat transfer, and cooling. If the oil temperature becomes too low or too high, compressor performance and reliability can be affected.

Function and Working Principle
The temperature control valve regulates compressor oil temperature by controlling oil flow through the oil cooling circuit.
A simplified oil circuit can be represented as:
Compressor Oil
↓
Temperature Control Valve
↓
Oil Cooler / Bypass Circuit
↓
Oil Filter
↓
Compressor Element
↓
Heat Generation
↓
Temperature Control
The valve responds to oil temperature and directs oil through an appropriate flow path.
During low-temperature operation, the valve can maintain oil circulation without sending the full oil flow through the cooler.
As oil temperature increases, the valve progressively directs more oil through the cooler so that excess heat can be removed.
The objective is to maintain oil within an appropriate operating temperature range.
Why the Temperature Control Valve Is Important
Compressor oil must remain within a suitable temperature range.
If the oil temperature is too low:
- Moisture may condense.
- Oil viscosity can increase.
- Lubrication characteristics may change.
- Oil circulation can become less effective.
- Compressor operating stability can be affected.
If the oil temperature is too high:
- Oil may degrade more rapidly.
- Lubrication performance can decrease.
- Compressor components can experience increased thermal stress.
- Oil carryover can increase.
- Compressor shutdowns may occur.
The temperature control valve therefore plays an important role in maintaining stable compressor operation.

Problem 10 – New Repair Kit Does Not Resolve the Problem
If the compressor continues to operate at abnormal temperatures after valve repair, inspect:
- Oil cooler
- Cooling fan
- Oil filter
- Oil level
- Oil quality
- Temperature sensors
- Compressor loading
- Ambient conditions
- Compressor internal condition
Not every temperature problem originates from the temperature control valve.

What are the dimensions of the repair kit?
The supplied dimensions are 100 × 15 × 80 mm.
What is the weight?
The supplied weight is 0.15 kg.
What happens if the temperature control valve is stuck?
A stuck valve can cause the compressor oil temperature to become too high or too low, depending on the valve’s failure position.
Why can compressor oil temperature become too high?
Possible causes include a malfunctioning temperature control valve, blocked oil cooler, poor airflow, incorrect oil level, high ambient temperature, or degraded oil.
Why can compressor oil temperature become too low?
A valve that directs excessive oil through the cooler can contribute to low oil temperature. Other possible causes include low ambient temperature or incorrect valve operation.
Can a faulty temperature control valve cause compressor overheating?
Yes. If the valve fails to regulate oil flow correctly, the compressor may not receive adequate oil cooling, potentially contributing to elevated operating temperatures.
Why should the oil cooler also be inspected?
A temperature problem may be caused by cooler blockage or insufficient airflow rather than the valve itself. The entire thermal management system should be checked.
How should the repair kit be maintained?
Inspect the temperature control valve during scheduled compressor service, checking valve movement, seals, contamination, oil temperature, and cooling-system performance.
When should the repair kit be installed?
A repair kit is appropriate when the existing temperature control valve has worn or damaged service components and the valve housing remains suitable for continued use.
Conclusion
The Ingersoll Rand 47704431001 47690563001 Temperature Control Valve Repair Kit is an important maintenance solution for compatible oil-injected compressor systems. The temperature control valve regulates oil flow through the cooling circuit, helping maintain suitable compressor oil temperature during startup, loading, and continuous operation.
