1,General:

HLPSL and HLPSV load-sensing proportional directional spool valves are mainly used in engineering machinery to control hydraulic cylinders or hydraulic motors. It is adaptable to manual; electric; hydraulic and pneumatic actuations to achieve step-less speed regulation, without effect of load change. Load-sensing characteristics can make multiple actuators work at different speed and pressure at the same time and independently till the maximum pump flow is reached.

HLPSL valve is designed for constant displacement pump system while HLPSV valve is designed for variable displacement pump system.

Load-sensing proportional directional spool valve is a combined type valve. Generally, it consists of connection Block, Directional Valve and End Plate. If necessary, ancillary blocks can be added on directional valves. Intermediate block could be added between directional valves.
