Short Description
The blowdown valve is a critical pressure control spare part for screw air compressors. It rapidly releases residual pressure inside the airend during unloading or shutdown, preventing damaging pressurized start-up and oil blowback, and ensures safe compressor operation. The valve body features high pressure resistance and corrosion resistance with OEM-level interchangeability. Compatible with Atlas Copco, Ingersoll Rand, Sullair and other mainstream screw air compressor brands.
Key Features
-
Fast pressure relief to protect airend Quickly vent residual air pressure inside the airend when unloading or shutting down. Avoid impact on rotors caused by pressurized start and oil blowback. Protect airend rotors and seals to extend compressor service life.
-
Heavy-duty valve body, pressure-resistant & anti-blocking High-quality brass valve body with excellent resistance to lubricating oil and compressed air corrosion. It can withstand the rated working pressure of air compressors for long-term continuous workshop operation. Resists air leakage and valve sticking after repeated cycles.
-
Precision valve core, sensitive & stable operation Precision-machined valve core delivers fast response and stable pressure switching. Passed fatigue cycle testing, low failure rate under frequent actuation, reducing unexpected downtime caused by abnormal pressure.
-
High OEM interchangeability, easy replacement Manufactured strictly in accordance with OEM drawings. Installation dimensions and thread ports match original parts perfectly. Simple disassembly and direct replacement to cut maintenance downtime.
-
Fix multiple common compressor failures Resolves typical issues: failure to unload, slow pressure venting, oil blowback after shutdown, trapped pressure and abnormal loading. Stabilize the whole compressed air system and reduce maintenance losses.

Notes
-
Please confirm compressor model, OEM part number and thread specification before ordering. For solenoid type blowdown valve, also confirm coil voltage.
-
Clean oil sludge and metal debris in pipelines before installation to prevent valve sticking and air leakage.
-
Blowdown valve is a wearing part. Regular inspection of valve core seals is recommended.
