Yuken MPA-01-2-4001 Pilot Operated Modular Check Valve D03 MPA0124001

Description:

The Yuken MPA-01-2-4001 Pilot Operated Modular Check Valve is used in hydraulic systems to allow free flow in one direction and controlled reverse flow via pilot pressure. 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 MPA-01-2-4001 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 mechanisms, presses, and automated machinery to prevent unintended movement, maintain position under load, and ensure safe and stable operation.
