16 A10V()O eries 31 Axial piston variable pump ED Electro-hydraulic pressure control ED Electro-hydraulic pressure control The ED valve is set to a certain pressure by a specified variable solenoid current. With changes on the consumer (load pressure), 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. As the solenoid current signal drops towards zero, the pressure will be limited to p max by an adjustable hydraulic pressure cut-off (secure fail safe function in case of power failure, e.g. for fan speed control). The response time characteristic curve of the ED control was optimized for the use as a fan drive system. When ordering, specify the type of application in plain text.

Axial piston variable pump A10V()O eries 31 ER Electro-hydraulic pressure control 17 ER Electro-hydraulic pressure control The ER valve is set to a certain pressure by a specified variable solenoid current. When a change is made at the consumer (load pressure), the position of the control spool will shift. 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. As the solenoid current signal drops towards zero, the pressure will be limited to p min (stand by).

Excessive current levels (I > 1200 ma at 12 V or I > 600 ma at 24 V) to the ER solenoid can result in undesired pressure increases which can lead to pump or system damage. Therefore: Use I max current limiter solenoids. An intermediate plate pressure controller can be used to protect the pump in the event of overflow. An accessory kit with intermediate plate pressure controller can be ordered from osch Rexroth under part number R902490825. RE 92701/06.2016, osch Rexroth AG
