Characteristics Series CPOM Pilot operated check valves from the Parker Manapak series CPOM are in sandwich design for easy configuration of stack systems. Depending on the function required, one or two pilot operated check valves are arranged in the ports and/or. he free flow direction is always from the valve side to the manifold side. Function he check valves open when flowing to the consumer side, where the opposing check valve is hydraulicallymechanically pilot operated simultaneously by a control spool, and thus the return flow is enabled from other consumer sides. CPOM3 Features he valve bodies of the Parker Manapak valve series CPOM are made of steel. he valve poppet is precisely guided into the steel sleeve and ensures a good seal on the seat. When the valve poppet is open, the large cross-section allows high flow rates at low differential pressure. Different control ratios can be chosen with the NG6 and NG10 valves.

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