Proportional Directional Valve 4WRKE25E1-220L-3X/6EG24TK31/F1D3M - Bosch Rexroth R900704759

When system pressure fluctuates while the return stays free of pressure, version TK is the right choice. In the 4WRKE25E1-220L-3X pilot oil comes in externally through X and drains internally, and a 4...20 mA current signal supplies the command value. It meters 220 l/min nominal flow at operating pressure up to 350 bar.

Benefits

• External pilot oil supply through X, internal pilot oil return
• 4...20 mA current command value at on-board electronics, 24 V DC
• 220 l/min nominal flow, flow rate up to 870 l/min
• Spool symbol E1, three switching positions, four ports
• 18.4 kg weight, operating pressure up to 350 bar, NBR seals

Applications

Valves of this kind work in accumulator driven presses and in systems whose pump switches to unloading at times. The pilot stage stays supplied through X and the valve keeps its control function. Mounting is on subplates to ISO 4401-08-08-0-05.
