Proportional Directional Valve 4WRZ10E1-85-7X/6EG24ETK4/V - Bosch Rexroth R901458968

The pilot-operated 4WRZ10E1-85-7X/6EG24ETK4/V proportional directional valve controls both direction and magnitude of flow to spool symbol E1. Nominal flow is 85 l/min and up to 170 l/min is possible. Control is handled by external electronics.

Benefits

• Nominal flow 85 l/min, maximum 170 l/min in size 10
• Continuous adjustment through external electronics at 24 VDC
• Spool symbol E1 with 3 switching positions and 4 ports
• Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05
• Internal pilot oil supply and internal pilot oil return, without pressure reducing valve
• FKM seals, 8.24 kg mass

Applications

Continuously adjustable directional valves are needed where speeds have to ramp up and down smoothly, for example on presses, test rigs and handling axes. As the unit is supplied without a pressure reducing valve, the pilot pressure in the circuit has to suit. The amplifier sits outside the unit and has to be ordered separately.

Manufacturer

Bosch Rexroth lists this valve under material number R901458968. Characteristic curves and pin assignment are given in datasheet RE 29115.
