YUKEN PILOT OPERATED CHECK MODULAR VALVE MPB-01-4-4001 MPB0144001

Description:

The Yuken MPB-01-4-4001 Pilot Operated Modular Check Valve is used in hydraulic systems to permit free flow in one direction and controlled reverse flow through pilot pressure release. Commonly installed in hydraulic power units, industrial presses, injection molding machines, and automated production equipment. Maintenance teams and system integrators use this part for load holding, circuit locking, retrofit, and replacement of faulty pilot operated check valves.

Applications:

The Yuken MPB-01-4-4001 pilot operated modular check valve is used in hydraulic circuits where secure load holding and controlled actuator movement are required. It is widely applied in lifting systems, clamping operations, presses, and automated machinery to prevent unintended actuator movement, maintain load position, and ensure safe and stable system performance.
