Atlas Copco Minimum Pressure Valve (MPV) Kit Replacement – 2910360200

Atlas Copco 2910360200 – Minimum Pressure Valve (MPV) Kit

The Atlas Copco 2910360200 (2910-3602-00) Minimum Pressure Valve (MPV) Kit is a service kit used for maintaining the minimum pressure valve assembly in rotary screw compressor systems. The MPV helps maintain the required minimum pressure inside the compressor’s oil-injected circuit and ensures proper operation of the oil circulation and air/oil separation system.

Working Process:
When the compressor starts, the minimum pressure valve remains substantially closed until sufficient internal pressure is developed within the compressor package. This allows the compressor to quickly build the minimum required internal pressure.

Once the internal pressure reaches the valve’s opening setting, the MPV opens and allows compressed air to flow toward the downstream air network. The valve regulates the passage so that adequate pressure is maintained inside the compressor separator vessel and associated circuit.

Maintaining this internal pressure is important for proper oil circulation. The pressure difference helps drive oil through the compressor’s lubrication and cooling circuit, allowing oil to reach the compressor element and other components that require lubrication and cooling.

During loaded operation, the MPV responds to the pressure conditions of the compressor and downstream system. It helps prevent the internal compressor pressure from falling below the required minimum level while still allowing compressed air to be delivered to the plant air system.

When the compressor unloads or stops, the valve closes or restricts the flow path. This helps isolate the compressor from downstream pressure and prevents unwanted reverse airflow into the compressor package.

The 2910360200 MPV Kit is used during maintenance when the valve’s internal components have become worn, contaminated, or damaged. Replacing the service components restores the valve’s ability to open, close, and regulate pressure correctly.

A malfunctioning minimum pressure valve can cause low internal pressure, poor oil circulation, excessive oil carryover, pressure instability, slow pressure build-up, or abnormal compressor operation. Regular inspection and replacement of worn MPV components therefore helps maintain compressor efficiency, reliable lubrication, and stable compressed-air delivery.

During servicing, the compressor must be isolated and completely depressurized before the MPV assembly is opened. The valve components are inspected, cleaned, and replaced with the appropriate components from the service kit. After reassembly, the valve should be checked for correct operation, leakage, and proper pressure regulation.
