Proportional Directional Valve 4WRZ10W8-85-7X/6EG24ETK4/V - Bosch Rexroth R900963716

The 4WRZ10W8-85-7X/6EG24ETK4/V proportional directional valve routes pilot oil supply and pilot oil return internally and therefore needs no additional control lines. Nominal flow is 85 l/min with a maximum of 170 l/min.

Benefits

• Internal pilot oil supply and internal pilot oil return, without pressure reducing valve
• Nominal flow 85 l/min, maximum 170 l/min in size 10
• Spool symbol W8, 3 switching positions, 4 ports
• Continuous adjustment through external electronics at 24 VDC
• 7.74 kg mass, connection diagram ISO 4401-05-05-0-05
• FKM seals, operating pressure up to 315 bar

Applications

Internal piloting shortens the piping to the four main ports and calls for a sufficient working pressure. The unit is used for metered feeds and soft reversing on presses, test rigs and handling axes. The matching amplifier sits outside the unit.

Manufacturer

Bosch Rexroth lists this valve under material number R900963716. The minimum pilot pressure required is given in datasheet RE 29115.
