Type
Valves
The ED valve is set to a certain pressure by a specified,variable solenoid current.
If there is a change at the consumer (load pressure),the position of the control piston changes.
This causes an increase or decrease in the pump swivel angle (flow) in order to maintain the electrically set pressure level.
The pump thus only delivers as much hydraulic fluid as the consumers can take. The desired pressure level can be set steplessly by varying the solenoid current.
