CompAir intake valve, cylinder piston, screw air compressor parts
Model: CompAir intake valve A11911874TD
Restore rapid modulation response and eliminate erratic loading cycles with this premium replacement CompAir Intake Valve Cylinder Piston Kit . Meticulously engineered to service demanding industrial rotary screw air compressor unloader manifolds, this high-precision pneumatic actuator component (Part Number: A11911874TD ) acts as the central mechanical driving force that physically shifts the intake valve plate between loaded, unloaded, and modulated operating states.
Manufactured from high-grade, wear-resistant engineering alloys and low-friction composite matrices , this internal piston kit is built to withstand millions of continuous operating cycles without structural warping or scoring. It features factory-ground tolerances that ensure a perfect, airtight glide along the unloader cylinder sleeve, reducing control air bypass to an absolute minimum. By replacing a leaking or sticking internal piston assembly with this plug-and-play kit, maintenance crews can instantly fix common "fail-to-load" faults, stabilize line pressure outputs, and lower the overall operational energy load on the primary compressor motor.
