12V&24V solenoid control hydraulic proportional valve

12V&24V solenoid control hydraulic proportional valve by current control with joysticks and wireless controller.  2series,3 series and 5 series. Made by Chinese factory.  3 Series Electro-Proportional Multi-Way Valve,Steel Hydraulic Control Valve,Propotional Directional Valve,Concrete Pump Valves 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…
