The MPW, MPA, and MPB series modular pilot-operated check valves are designed to allow unrestricted flow in one direction while reliably preventing flow in the opposite direction. These valves are used to lock the actuator in the neutral position, ensuring position stability. When the directional control valve is actuated, a pilot pressure signal is automatically applied, releasing the check function and restoring motion. Depending on system requirements, these valves can be configured to operate in ports A, B, or both.
