Seven Ocean Hydraulics CPDG Series Pilot Controlled Check Valves are much like direct operated valves, they permit free flow in one direction and prevent flow in the reverse direction, however, pilot operated valves permit reverse flow when a pilot pressure signal is applied to the valve's pilot port.

The valve consists of 2 poppets, a main poppet and a decompression poppet which is much smaller than the check valve's pilot piston. During operation, the decompression poppet opens first, reducing the pressure behind the main poppet that is holding the main poppet closed. When this pressure is low enough, the pilot piston pushes the main poppet into the open position to allow full reverse flow.
