Atlas Copco Minimum Pressure Valve Maintenance Kit Replacement – 2901139900

The Atlas Copco 2901139900 Minimum Pressure Valve Maintenance Kit (MPV Kit) is a genuine OEM service kit designed for selected Atlas Copco oil-injected screw air compressors. The minimum pressure valve (MPV) is a critical component of the compressor oil separation system that maintains the required minimum pressure inside the separator vessel. This ensures proper oil circulation, efficient lubrication of the airend, and stable compressor operation. The valve also prevents compressed air backflow into the compressor during shutdown.

Manufactured according to Atlas Copco’s OEM quality standards, the 2901139900 MPV Kit contains precision-engineered internal valve and sealing components required to restore the original performance of the minimum pressure valve assembly. The kit helps maintain accurate pressure regulation, reduce internal leakage, improve compressor efficiency, and extend equipment service life.
