14 14 10VO series 32 xial piston variable pump DRF/DR Pressure and flow control DRF/DR Pressure and flow control In addition to the pressure control function (see chematic DG page 12), a variable orifice (e.g. directional valve) is used to adjust the differential pressure upstream and downstream of the orifice. This is used to control the pump Plugged at DR valve flow. The pump flow is equal to the actual required flow by the consumer, regardless of changing pressure levels. The 1 pressure control overrides the flow control function. Note The DR valve version has no connection between and the reservoir. Unloading the L-pilot line must be possible in the valve system. Because of the flushing function, sufficient unloading of the -line must also be provided.

17 xial piston variable pump 10VO series 32 ED Electro-hydraulic pressure control 17 ED Electro-hydraulic pressure control The ED 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 piston 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. s 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 a loss of power, e.g. for fan drives ). 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 clear text.
