Characteristics Pilot operated check valves series ZRE are designed for maximum flow rates and long life time. The valves are typically used in combination with spool type directional control valves to ensure leak free positioning of the actuator. The inlet flow is free while the outlet flow is blocked. Pressure in the inlet line opens the check valve and allows free outlet flow.
