Spool symbol and nominal flow both have to match when a proportional valve is replaced, otherwise the control behaviour of the axis changes. The 4WRZ10W8-85-7X/6EG24ETK4/D3M combines W8 with 85 l/min, is piloted internally and weighs 8.24 kg.

Total price
Replacing an installed valve carrying symbol W8 also means matching its nominal flow. The 4WRZ10W8-85-7X/6EG24ETK4/D3M supplies both, along with internal pilot supply and internal return at a maximum operating pressure of 315 bar.
Benefits
- Spool symbol W8 at 85 l/min nominal flow, flow range up to 170 l/min
- Internal pilot routing for supply and return, without external ports
- Integrated pressure reducing valve for a limited pilot pressure
- 315 bar maximum operating pressure, ISO 4401-05-05-0-05 interface
- 24 VDC through external electronics, 7-pole (6 + PE) connector to EN 175201-804
- 8.24 kg in size 10, 3 switching positions, 4 ports

Applications
It serves controlled feed and lifting axes whose command value comes from an amplifier card. Because symbol and nominal flow follow the installed base, the ramps already set in the controller remain valid. The NBR seals are matched to HL hydraulic fluid.
Manufacturer
Bosch Rexroth lists the valve as R900246100. The relation between symbol, nominal flow and curve is set out in data sheet RE 29115, supplemented by RE 07600-B.
