Proportional Directional Valve 4WRZ10E25-7X/6EG24N9K4/D3M - Bosch Rexroth R901057740

Where the pilot circuit has to stay separate from the working circuit, the 4WRZ10E25-7X/6EG24N9K4/D3M fits: it takes pilot oil externally and returns it externally while setting a nominal flow of 25 l/min to symbol E in size 10.

Benefits

• External pilot oil supply and external pilot oil return
• Nominal flow 25 l/min, maximum flow 170 l/min
• Symbol E with three switching positions and four ports
• Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05
• Weight 8.2 kg, supply voltage 24 VDC
• NBR seals for HL hydraulic fluid

Applications

The variant makes sense in systems with a dedicated pilot pump, for example on test rigs and machine tools. The separate return keeps the pilot pressure independent of the tank pressure of the working circuit. Mounting is on a plate to ISO 4401-05-05-0-05.
