Atlas Copco Blow Off Valve Replacement – 1622369480

The Atlas Copco 1622369480 Blow Off Valve (Unloader Valve Kit) is a genuine OEM valve assembly designed for selected Atlas Copco oil-injected screw air compressors. The blow-off valve is a critical component of the compressor unloading system, responsible for releasing trapped pressure from the compressor system during unloading and shutdown cycles. This ensures smooth compressor operation, reduces starting load on the motor, and helps maintain reliable pressure control.

Manufactured according to Atlas Copco’s strict OEM standards, the 1622369480 Unloader Valve Kit provides accurate pneumatic control, reliable sealing, and long service life in demanding industrial environments. The valve assembly helps regulate compressor loading and unloading sequences, preventing excessive pressure buildup and improving overall system efficiency.
