Dual Pilot operated check valves (also referred to as P.O. check valves), are check valves which can be opened by an external pilot pressure. Thus, P.O.checks, block flow in one direction, like standard check valves, but can be released once an adequate pilot pressure is applied.

Free flow is allowed in the reverse direction. Dual P.O.checks are often used to positively lock a dual acting cylinder. There
are two types of pilot operated check valves; threaded cartridge style and pilot piston style. These valves work best when used in conjunction with a control valve that vents the valve ports to tank when centered.  Also, they should be used when a metering condition is NOT expected.
