Proportional Directional Valve 4WRKE32W8-600P-3X/6EG24EK31/A1D3M - Bosch Rexroth R901206705
In size 32 every pilot line saved is a gain in the manifold. The 4WRKE32W8-600P-3X/6EG24EK31/A1D3M draws pilot pressure internally, routes the return outside and controls 600 l/min nominal flow at 350 bar.

Description
On large valves the piping quickly becomes hard to follow. The 4WRKE32W8-600P-3X/6EG24EK31/A1D3M manages on internal pilot oil supply and needs only the external pilot return, at 600 l/min nominal flow and up to 1600 l/min maximum flow.
Benefits
- Internal pilot oil supply, no dedicated feed line for the pilot stage.
- External pilot oil return, independent of back pressure in the tank line.
- 600 l/min nominal flow, up to 1600 l/min maximum flow.
- 350 bar operating pressure, connection diagram ISO 4401-10-09-0-05.
- Symbol W8, linear characteristic with a fine control range, command value ±10 V.
- 36.86 kg, NBR seals, on-board electronics at 24 V DC.
Applications
The valve sits in main axes of large forming plants where system pressure is present continuously anyway. Because only one pilot line leaves the valve, the manifold stays leaner than with versions using a separate pilot feed.
Manufacturer
Bosch Rexroth, material number R901206705, product family 4WRKE. The 6EG24EK31 code in the type designation covers electronics together with pilot oil routing.
