Proportional Directional Valve 4WRKE25W8-350L-3X/6EG24EK31/F1D3M - Bosch Rexroth R900705057

Anyone moving large flow rates against a loaded return line needs a separate pilot drain. The 4WRKE25W8-350L-3X takes pilot oil internally and leads it away through Y, metering 350 l/min nominal flow at operating pressure up to 350 bar from a 4...20 mA command value.

Benefits

• Internal pilot oil supply, external pilot oil return through Y
• 350 l/min nominal flow, flow rate up to 870 l/min
• 4...20 mA current command value, 24 V DC supply
• Spool symbol W8, four ports, three switching positions
• 17.92 kg weight, operating pressure up to 350 bar

Applications

The combination is needed on presses and lifting gear whose return runs through coolers and filters. Through the Y port the pilot stage stays unaffected by them. Electrical connection is by a 7-pole connector (6 + PE) to EN 175201-804.
