piston valve / hydraulic / pressure-control / overcenter

Load holding valves are also pressure valves and the return duct is blocked according to the level of the return pressure. There is a setting of approximately 15% above the maximum load pressure to generate a counter force to a pushing negative load. Type LHK is designed for applications that hardly have oscillations. Directional spool valves have multiple options that are available including shutter valves, shock valves, valves with or without bypass check. Type LHT features simplicty while type LDHV comes with an elaborate special dampening equipment making them perfectly suited for applications together with props.
