Proportional Directional Valve 4WRKE25W6-350L-3X/6EG24TK31/A1D3M - Bosch Rexroth R900701431

If pilot pressure comes from a circuit of its own while the return goes into the shared tank anyway, one line can be saved. The 4WRKE25W6-350L-3X/6EG24TK31/A1D3M is laid out exactly like that and delivers 350 l/min nominal flow with symbol W6.

Technical data

Applications

The variant fits power units with a pilot pump whose tank channel shows little back pressure. Symbol W6 keeps the axis finely controllable even at small signal levels. With 350 l/min nominal flow the valve serves lifting, feed and clamping axes on presses and forming machines.
