The Ingersoll Rand 47627051001 22067177 Inlet Valve Repair Kit is a service kit for the inlet valve assembly used in compatible rotary screw air compressors. The inlet valve controls the entry of ambient air into the compression stage and participates in the compressor’s loading and unloading process. When its internal mechanism no longer moves or seals correctly, the compressor may struggle to build pressure, respond slowly to operating commands, or unload improperly.
In an oil-injected rotary screw compressor, the inlet valve is located upstream of the air end. During loading, it opens to admit air into the screw element. When the compressor needs to reduce or stop air production, the valve changes position according to the machine’s control sequence. The valve’s movement must correspond with the control system’s commands for the compressor to operate as intended.
The 22067177 repair kit is associated with the inlet valve unloader mechanism used in selected Ingersoll Rand UP6 compressor configurations, including certain UP6-20, UP6-25, and UP6-30 machines. The kit is intended for servicing the compatible valve assembly rather than automatically replacing the complete valve. Its actual contents and fitment should be confirmed against the installed configuration before maintenance begins.
A typical maintenance situation occurs when a compressor takes longer than usual to reach the required discharge pressure. If the inlet valve sticks or its internal sealing components deteriorate, the amount of air entering the compression stage may not match the controller’s demand. In other cases, the valve may fail to close as expected during unloading, leaving the machine operating differently from its intended sequence.
These symptoms do not automatically establish an inlet valve fault. A restricted intake filter, insufficient actuator pressure, a malfunctioning solenoid valve, or an incorrect control signal can produce similar behavior. A proper diagnosis should establish whether the problem lies inside the valve assembly or in the mechanism responsible for moving it.
For maintenance engineers, the practical purpose of the 22067177 kit is to address serviceable components within the applicable inlet valve assembly. Correct repair involves more than fitting replacement parts: the valve must move freely, seal at the required positions, and respond correctly when the compressor changes between loaded and unloaded operation.

The inlet valve regulates how much air enters the compressor’s screw element. Its position is controlled by the compressor’s loading and unloading arrangement, which may use an actuator and pneumatic or solenoid-operated control circuit depending on the machine configuration.
Ambient Air → Intake Filter → Inlet Valve → Rotary Screw Air End → Oil Separation System → Compressed Air Outlet
When compressed air is required, the controller commands the compressor to load. The inlet valve moves toward its open position, allowing ambient air to enter the compression chamber. The rotating screw elements compress this air, and the resulting air-oil mixture proceeds through the separation system.
When demand falls, the controller may initiate unloading. The inlet valve moves toward its designated unloaded position, reducing the air entering the air end. Other components in the unloading arrangement may also manage internal pressure during this transition. The exact sequence depends on the compressor’s control design.
The inlet valve must respond consistently to these commands. If an internal component sticks, a spring loses its intended behavior, or a sealing surface deteriorates, the valve may not achieve the required position. The compressor can then experience delayed pressure buildup, incomplete unloading, or irregular operating behavior.
The 22067177 repair kit is used when inspection identifies a fault in the serviceable components of the compatible inlet valve assembly. The precise contents should be verified before disassembly, and the condition of the valve body should be assessed to determine whether a kit repair is sufficient.
If the valve does not move correctly after servicing, the investigation should extend to the actuator, pilot air supply, solenoid valve where fitted, and controller output. A mechanically sound valve cannot operate correctly if its control circuit fails to deliver the required movement.
The inlet valve connects the compressor’s air intake path with its capacity control function. Its position determines whether the air end receives incoming air for compression or operates in the designated unloaded condition.
Intake Filter → Inlet Valve Assembly → Screw Air End → Oil Separator → Aftercooler → Plant Air Network
The control sequence operates alongside this airflow path. The compressor controller evaluates operating requirements and issues the commands that govern loading and unloading. The actuator and associated control circuit translate those commands into movement of the inlet valve.
| System Component | Function |
|---|---|
| 22067177 Inlet Valve Repair Kit | Services the compatible inlet valve mechanism |
| Inlet Valve Assembly | Controls incoming air to the compression stage |
| Intake Air Filter | Removes airborne contaminants from incoming air |
| Valve Actuator | Moves the inlet valve in response to the applicable control arrangement |
| Solenoid Valve, Where Fitted | Controls the relevant pilot or pneumatic circuit |
| Control Air Supply | Provides actuation pressure where the valve uses pneumatic control |
| Compressor Controller | Coordinates loading, unloading, and operating commands |
| Rotary Screw Air End | Compresses the incoming air |
| Oil Separator Element | Separates entrained oil from compressed air |
| Minimum Pressure Valve | Maintains the required internal pressure conditions and controls downstream flow |
| Aftercooler | Reduces compressed air temperature before delivery |
| Pressure Sensors | Provide operating feedback for monitoring and control |
The repair kit addresses the valve mechanism, not every component involved in capacity control. Correct operation after maintenance depends on the condition of the valve, the actuator, and the associated control circuit.
| Application | Typical Use |
|---|---|
| Automotive Manufacturing | Maintaining inlet valve operation in compressors supplying assembly lines and pneumatic tools |
| Metalworking Facilities | Servicing intake control mechanisms in compressors supporting machine tools and production equipment |
| Packaging Plants | Maintaining loading and unloading response as compressed air demand changes |
| General Manufacturing | Supporting routine maintenance of central compressed air installations |
| Plastics Processing | Addressing valve faults in compressors supplying pneumatic production machinery |
| Textile Manufacturing | Maintaining compressor intake control in facilities with continuous pneumatic demand |
| Industrial Assembly | Servicing inlet valve mechanisms in compressors used with air-powered tools |
| Material Handling | Supporting compressor capacity control in pneumatic conveying installations |
| Central Compressor Rooms | Maintaining inlet valve operation in shared compressed air systems |
| Continuous-Production Facilities | Addressing valve wear that affects compressor response during extended operating shifts |
The kit is suitable for these maintenance situations only where the installed compressor uses the corresponding inlet valve configuration. Compressor horsepower or series designation alone is not sufficient to establish part compatibility.
If the compressor continues to exhibit slow pressure buildup or incomplete unloading, inspect the actuator, control air supply, solenoid circuit where fitted, and intake filter before concluding that the valve repair has failed.

A repair kit contains specified service components for the applicable valve mechanism, whereas a complete assembly replaces the valve as a unit. The exact contents of 22067177 should be confirmed against its parts list. If the valve body or critical seating surfaces are damaged, servicing the internal components may not be sufficient.
The valve may still be sticking, or its actuator may not be receiving the required control pressure or signal. A faulty solenoid valve, blocked control passage, or incorrect controller command can also prevent unloading. The mechanical valve and its control circuit should be tested separately.
The kit is associated with selected Ingersoll Rand UP6-20, UP6-25, and UP6-30 configurations, as well as certain related UP6S versions. Because valve designs and parts configurations can vary, confirm the full compressor identification and installed valve reference before selecting the kit.
Check that the inlet valve moves through its intended range and that the actuator and control circuit operate correctly. Also inspect the intake filter for restriction and investigate other causes of reduced capacity, such as internal leakage or faults elsewhere in the compressor. The original symptom should be reassessed rather than assuming another valve kit is required.
