Product Overview

The Ingersoll Rand 47704433001 / 47690563001 Temperature Control Valve Repair Kit is a maintenance component designed for servicing the temperature control valve assembly used in compatible Ingersoll Rand rotary screw compressors.

The temperature control valve is an important part of the compressor oil circulation system. Its primary function is to help regulate the temperature of compressor oil by controlling the oil flow through the oil cooler according to operating conditions.

During compressor operation, maintaining the correct oil temperature is essential. Oil that is too cold can reduce moisture separation and may contribute to condensation, while excessive oil temperature can negatively affect lubrication, cooling, and compressor performance.

The 47690563001 repair kit is intended for rebuilding or servicing the applicable temperature control valve rather than replacing the complete compressor assembly. It can therefore be useful during scheduled preventive maintenance or when inspection indicates that the valve’s internal components have become worn or damaged.

With supplied dimensions of 100 × 15 × 80 mm and an approximate weight of 0.15 kg, the kit is compact and suitable for compressor maintenance inventory.

Technical Specifications

The 100 × 15 × 80 mm dimensions and 0.15 kg weight are the supplied product specifications for this repair kit. Individual internal components contained in the kit may have different dimensions and weights.

Function and Working Principle

The temperature control valve controls the path taken by compressor oil as the compressor reaches its operating temperature.

A simplified oil circulation path can be represented as:

Oil Separator / Sump → Temperature Control Valve → Oil Cooler → Oil Filter → Airend

The valve responds to oil temperature and directs oil through the appropriate circuit.

When the compressor is starting and the oil temperature is relatively low, the valve can reduce or restrict oil flow through the cooler, allowing the oil to reach its normal operating temperature more quickly.

As the oil temperature increases, the valve progressively directs more oil through the oil cooler. The cooled oil is then returned to the compressor lubrication circuit.

This temperature-regulating function helps maintain the oil within an appropriate operating range.

The valve therefore contributes to:

• Oil temperature control
• Compressor cooling
• Lubrication stability
• Moisture management
• Airend protection
• Stable compressor operation

Role in Industrial Compressed-Air Systems

The 47704433001 / 47690563001 repair kit is used within the compressor’s oil management system rather than the electrical control system.

A typical oil-injected screw compressor contains several interconnected systems:

Air Intake → Airend → Air/Oil Separator → Compressed-Air Outlet

and:

Oil Separator → Temperature Control Valve → Oil Cooler → Oil Filter → Airend

The temperature control valve sits in the second circuit and determines how much oil is routed through the cooler.

Correct oil temperature is important because compressor oil performs several functions simultaneously, including:

• Lubricating moving components
• Removing heat
• Supporting sealing inside the airend
• Reducing component wear
• Protecting internal compressor parts

If the temperature control valve becomes defective, the compressor may experience abnormal oil temperature, insufficient cooling, excessive cooling, or unstable operating conditions.

Why the Temperature Control Valve Is Important

The compressor’s oil temperature has a direct relationship with overall equipment performance.

If the valve remains too closed, insufficient oil may pass through the cooler, potentially causing elevated oil temperature.

If the valve remains too open, excessive cooling can occur, particularly during low-load or low-ambient-temperature conditions.

Possible symptoms of temperature control valve problems can include:

• High compressor oil temperature
• Slow warm-up
• Abnormally low operating temperature
• Compressor thermal alarms
• Reduced cooling efficiency
• Oil-related operating problems
• Increased maintenance requirements

A suitable repair kit allows worn valve components to be replaced so that the existing valve assembly can return to normal operation.

Industrial Applications

The Ingersoll Rand 47704433001 / 47690563001 repair kit is primarily used for maintenance of compatible industrial air compressors.

Manufacturing Plants

Compressed air is widely used for pneumatic tools, actuators, automation equipment, packaging systems, and production machinery.

Automotive Manufacturing

Assembly lines and automotive production facilities depend on reliable compressed-air systems for tools and automated equipment.

Chemical and Process Industries

Continuous compressor operation makes proper oil temperature management especially important.

Food and Beverage Plants

Compressed air is used for packaging, conveying, instrumentation, and various pneumatic systems.

General Industrial Facilities

The kit can be used as part of preventive maintenance programs for compatible Ingersoll Rand rotary screw compressors.

Installation and System Integration

The temperature control valve repair kit should be installed by qualified compressor maintenance personnel.

A typical service procedure includes:

1. Stop the compressor.
2. Isolate the compressor from the compressed-air system.
3. Release all stored pressure.
4. Allow the compressor and oil system to cool.
5. Drain or manage compressor oil as required by the service procedure.
6. Remove the temperature control valve assembly.
7. Inspect the valve body and internal components.
8. Replace the applicable components using the repair kit.
9. Reassemble the valve correctly.
10. Reinstall the valve into the oil circuit.
11. Restore the oil system and connections.
12. Start the compressor and verify operating temperature.

After maintenance, technicians should check for:

• Oil leakage
• Abnormal oil temperature
• Correct compressor loading
• Proper cooling operation
• Stable operating pressure
• Abnormal alarms
• Unusual temperature fluctuations

Because the valve is part of a pressurized and hot oil system, maintenance should only be performed after the equipment has been safely isolated and depressurized.

Compatible System Components

The temperature control valve repair kit operates as part of the compressor oil circulation system.

These components work together to maintain proper compressor lubrication and thermal performance.

Recommended Alternative Models

Temperature control valve repair kits are generally compressor-specific, so the correct replacement should be determined from the compressor model and original valve configuration.

The 47690563001 should not be replaced simply because another valve repair kit has similar physical dimensions. Valve temperature characteristics, compressor model, internal design, and service specifications must all be considered.
