Proportional Directional Valve 4WRKE25E1-350L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901218003

Large cylinders call for flow rate without giving up control quality. At 350 l/min nominal flow and a maximum of 870 l/min the 4WRKE25E1-350L-3X covers rapid traverse and meters the creep feed on the same characteristic curve. Pilot oil comes internally from the P line, the return runs externally through Y.

Benefits

• 350 l/min nominal flow, flow rate up to 870 l/min
• Linear characteristic curve across the full 4...20 mA command range
• Internal pilot oil supply, external pilot oil return
• Operating pressure up to 350 bar, four ports, three switching positions
• 17.86 kg weight, NBR seals, HL hydraulic fluid

Applications

Suited to press cylinders, forging equipment and lift tables where a long rapid stroke turns into a controlled working movement. The on-board electronics sit directly on the valve and save an amplifier card in the cabinet. Wiring uses the 7-pole connector (6 + PE) to EN 175201-804.
