Introduction
The Ingersoll Rand 47553881001 / 23467251 Intake Valve Service Kit listing combines an 8K intake-valve maintenance reference with a dedicated actuator-cylinder service reference.
47553881001 is cataloged as an Intake Valve Service Kit 8K (with modification) for the R90–160, IR90–160, and IE R90–160 compressor family. It is listed alongside the related 47553880001 intake-valve service kit, but the two part numbers should not be assumed interchangeable because 47553881001 is specifically identified as the modified version.
The second reference, 23467251, is a service cylinder kit. Ingersoll Rand parts documentation identifies it as “KIT, SERVICE ACTUATOR CYLINDER (HAKG/HPKG 80, 110, 120 & 140)”, while other parts listings specify HPKG 110/120/140.
The intake valve is a key component in a rotary screw compressor's air-management system. It controls the quantity of atmospheric air admitted into the airend and participates in the compressor's capacity-control sequence.
The actuator cylinder provides the mechanical movement required to position the associated valve. Pneumatic control pressure acts on the cylinder, producing movement of the piston and rod assembly. If the cylinder loses sealing or develops mechanical resistance, the valve may not respond correctly to the control signal.
This makes actuator condition important during intake-valve troubleshooting. A compressor that exhibits abnormal loading, unloading, or modulation behavior may have a problem with the intake valve itself, the actuator cylinder, the solenoid-control circuit, pneumatic tubing, or another associated component.
23467251 is intended as a service kit, rather than simply a generic replacement cylinder. Its purpose is to refresh the internal service components of the actuator-cylinder assembly when the existing unit remains suitable for rebuilding.
Correct sealing is particularly important in a pneumatic actuator. Worn internal sealing components can allow pressure to bypass the piston, reducing actuator force and slowing or preventing correct valve movement.
Mechanical condition is equally important. Contamination, corrosion, damaged surfaces, or excessive friction can interfere with smooth cylinder movement even when the pneumatic control signal itself is correct.
For scheduled maintenance, the 8K designation on 47553881001 identifies the applicable service classification. Actual replacement procedures should follow the maintenance requirements for the specific compressor and control configuration rather than relying on operating hours alone.
The R90–160 parts family contains several closely related references. For example, 47553880001 is separately cataloged as an 8K intake-valve service kit, while 47552954001 is a temperature-control valve maintenance kit. These parts address different functions and should not be substituted simply because they share the same compressor family.
The 23467251 service cylinder also needs careful application matching. One parts reference identifies the component for HAKG/HPKG 80, 110, 120, and 140, while current commercial documentation focuses on HPKG 110/120/140. This difference makes model and serial-number verification important when ordering.
A trade record independently identifies 23467251 as a service cylinder kit for HPKG 110/120/140, further supporting its function as an actuator-cylinder service component rather than a complete intake-valve assembly.
Exact internal contents of 47553881001 were not fully verified from the available public technical documentation. Likewise, the complete contents of 23467251 should be confirmed against the applicable parts list before assuming that every seal, piston component, or hardware item is included.
Exact engineering dimensions for the complete kits were also not reliably established. A third-party product page presents 23467251 as an actuator-cylinder service kit, but does not provide a dependable dimensional drawing or certified package dimensions.
The supplied pair is treated as one product listing as requested. Public records independently establish 47553881001 as the modified 8K intake-valve service kit and 23467251 as the actuator-cylinder service kit for compatible HPKG/HAKG configurations.
