Proportional Directional Valve 4WRKE25E350L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R900704202

High flow does not have to mean more piping. The 4WRKE25E350L-3X/6EG24ETK31/A1D3M feeds and drains pilot oil internally, so despite 350 l/min nominal flow the manifold needs only its four working ports, operating pressure up to 350 bar.

Key benefits

• Pilot oil fed and drained internally, piping stays limited to what is actually needed.
• 350 l/min nominal flow in size 25, maximum flow 870 l/min.
• Spool symbol E, 3 switching positions, 4 ports, connection pattern ISO 4401-08-08-0-05.
• Plus minus 10 V command, 24 VDC supply, on-board electronics without an amplifier card.
• Internal spool position feedback, linear characteristic curve, NBR seals for HL hydraulic fluid.
• 17.76 kg weight, 7-pole connector (6 + PE) to EN 175201-804.

Applications

Sensible in densely populated valve blocks where there is no room left for additional pilot drillings. At 350 l/min nominal flow the valve also moves larger main cylinders briskly. A closed pilot stage cuts the number of fittings and with it the possible leak points.
