Product Overview
The Ingersoll Rand 47667846001 47661613001 Screw Compressor Intake Valve Repair Kit is a service kit for maintenance and repair of compatible screw compressor intake valve assemblies. It is used when the intake valve requires refurbishment of serviceable components rather than replacement of the complete valve assembly.
The intake valve controls the entry of air into the compressor airend. Its operating condition affects how the compressor loads, unloads, and responds to changing air demand. Worn or damaged valve components can contribute to abnormal loading behavior, leakage, or reduced compressor performance.
During compressor servicing, the repair kit can be used to replace designated wear or sealing components within the intake valve assembly. This is particularly useful during planned overhauls or corrective maintenance where inspection identifies deterioration in the valve mechanism.
The kit should be matched to the specific compressor and intake valve configuration before installation. Component orientation, sealing surfaces, mechanical movement, and the final loading and unloading response should be checked as part of the repair procedure.

Product Features
- Repair kit for compatible screw compressor intake valve assemblies.
- Supports service and refurbishment of intake valve components.
- Intended for maintenance of compressor air-intake control mechanisms.
- Useful for scheduled compressor overhaul and corrective repair.
- Can address serviceable wear or sealing components within the valve assembly.
- Supports restoration of proper intake valve movement and operation.
- Helps reduce the need for complete valve replacement when the existing assembly is serviceable.
- Requires verification against the applicable compressor configuration before use.
Working Principle
The intake valve regulates the amount of air entering the screw compressor airend according to the compressor’s operating condition. During loading, the valve allows the required inlet flow into the compression chamber. During unloading or reduced-demand operation, the valve position changes to limit or control intake flow.
The repair kit restores selected mechanical and sealing components within the valve assembly so that the valve can move correctly and maintain the intended operating relationship with the compressor control system.
Air Intake → Intake Valve → Screw Compressor Airend → Compressed Air System
When the serviced valve responds correctly to the compressor control signal, inlet airflow can be adjusted according to demand. A sticking valve, damaged sealing component, or mechanically worn part can interfere with this response and may result in abnormal loading, unloading, or pressure behavior.
Role in a Screw Compressor Air Intake Control Architecture
The 47667846001 47661613001 belongs to the mechanical service layer of the compressor intake-control system. It does not perform electronic control itself; instead, it supports the mechanical condition of the intake valve that responds to the compressor’s control strategy.
Compressor Controller → Intake Control Mechanism → Intake Valve → Airend → Compressed Air System

Installation and Maintenance
- Verify the 47667846001 47661613001 part number against the compressor and intake valve documentation before use.
- Confirm that the repair kit matches the specific intake valve assembly being serviced.
- Isolate the compressor and release stored pressure before beginning maintenance.
- Document the original valve configuration and component orientation before disassembly.
- Inspect the intake valve for contamination, wear, corrosion, sticking, or mechanical damage.
- Clean applicable valve and sealing surfaces using an approved maintenance procedure.
- Replace the designated service components included in the repair kit according to the applicable instructions.
- Check that seals, springs, moving parts, and other service components are correctly positioned where applicable.
- Reassemble the intake valve and verify free mechanical movement before returning the compressor to service.
- Inspect all related pneumatic or control connections for leakage or incorrect installation.
- Restore the compressor under controlled conditions and verify loading, unloading, and intake response.
- Record the repair and functional test results before returning the compressor to normal operation.

Technical FAQs
What compressor symptoms can indicate an intake valve problem?
Abnormal loading or unloading, unstable pressure behavior, excessive air consumption during unloaded operation, or delayed response to operating commands can justify inspection of the intake valve. The control system and pneumatic components should also be checked before identifying the valve as the root cause.
Does the repair kit replace the complete intake valve assembly?
The kit is intended for repair of designated service components within a compatible intake valve assembly. Whether the complete valve can remain in service depends on the condition of its body, moving mechanism, sealing surfaces, and other components.
Why is component orientation important during intake valve repair?
The intake valve depends on the correct relationship between its mechanical and sealing components. Incorrect orientation or assembly can restrict valve movement, cause leakage, or change the compressor’s loading and unloading behavior.
How should intake valve operation be verified after the repair?
After reassembly, the compressor should be started under controlled conditions and the intake valve response observed through the loading and unloading sequence. Pressure behavior, valve movement, leakage, and the compressor’s normal operating response should all be checked before full operation.
