PARKER HANNIFIN part description

Parker’s Parker LO & LOA Pilot Operated Check valves provide load holding where fluid leakage through the control valve may adversely affect the performance of the system such as clamps, outriggers, and work platforms. Additionally, they can be applied to prevent movement of a load while the pressure source is inactive and a control valve is inadvertently actuated.

A control valve with a free flow (motor) spool should be used on any circuit which includes a Pilot Operated Check. This spool option will prevent unwanted pressure build up between the Control valve and Pilot Operated Check Valve.
