EThan EDG valve is a type of proportional directional valve that is used for controlling the flow of fluid to actuators in hydraulic systems. It is available in either on-off or proportional versions and features circuit modularity, compact dimensions, light weight and load-sensing for system energy savings.
— They can adjust system pressure proportionally base on input electricity of proportional solenoids.
— It’s flow is small nad usually is used as pilot valve for system pressure telecontrol valve and other valves.
— The unloading when pressure is over loading can be come true by installing safe insert file , then it can protect proportional solenoid and system
