Load-holding valve type LHK, LHDV and LHT
Load-holding valves are a type of pressure control valve. They prevent loads on cylinders or motors dropping in an uncontrolled manner. For this purpose they are pre-loaded with a pressure setting that is higher than the largest possible load. A hydraulic piston controls the opening of the valve to achieve the required lowering velocity. The load-holding valves type LHK and LHT are suitable for applications that are not particularly prone to oscillations. The load-holding valve type LHDV has special damping characteristics. It is used particularly in conjunction with proportional directional spool valves, e.g. type PSL and PSV. Shock valves and shuttle valves with or without restrictor check valves can be tted in the load-holding valves type LHK, LHDV and LHT, e.g. to relieve hydraulic brakes with a delay.
