Product Overview
Intake Valve Diaphragm Cup is a vital rubber wearing part for the servo cylinder of screw air compressors. It drives the servo‑cylinder piston through rubber deformation to realize accurate loading and unloading cycles. Under long‑time operation, constant high‑temperature oil‑gas erosion and millions of repeated flexing cycles will cause hardening, swelling, cracking or rupture. The damaged diaphragm leads to common troubles including failure to load, big pressure fluctuation, air leakage during unloading, rapid pressure drop after shutdown and excessive energy consumption. Timely replacement restores precise intake‑valve control, protects the whole intake valve assembly and cuts unplanned downtime losses. This aftermarket replacement follows OEM specification with identical curvature and mounting holes for direct drop‑in installation.
Key Features
✅ Oil‑resistant & Heat‑resistant Industrial‑grade Rubber Made of reinforced synthetic rubber compound. Excellent resistance to compressor oil corrosion and continuous high working temperature. Outstanding anti‑fatigue performance, resisting hardening, swelling and cracking after millions‑time flexing cycles. Perfect for 24‑hour heavy‑duty industrial operation and longer service life.
✅ Integrated Precision Moulding & Excellent Sealing Performance One‑piece moulding ensures identical cup curvature and flange hole layout as original parts. Uniform deformation and stable rebound eliminate control‑air leakage. Guarantees fast load‑unload response, fixes unstable pressure and slow pressure build‑up, reduces unnecessary energy waste.
✅ OEM Direct‑fit Design, Time‑saving Maintenance Fully matches original dimension. No trimming or secondary modification required for direct replacement. Shortens equipment downtime and cuts on‑site labor maintenance cost.
✅ Sensitive Actuation & Full‑valve Protection Smooth and gentle driving force cushions impact inside servo cylinder. Prevent valve jamming caused by broken rubber fragments, so as to protect internal piston, spring and other components and extend the service life of the complete intake valve.
