Proportional Directional Valve 4WRTE25W8-350L-4X/6EG24EK31/A1M - Bosch Rexroth R900703226

With high system pressure the internal pilot oil supply is sufficient, while a drain free of back pressure often has to be routed separately. This version combines both and transfers 350 l/min nominal flow at 350 bar.

Benefits

• Internal supply with external pilot oil return keeps the pilot stage clear of back pressure.
• 350 l/min nominal flow at 350 bar operating pressure.
• Up to 870 l/min flow in size 25, connection diagram ISO 4401-08-08-0-05.
• Spool symbol W8, 3 switching positions, ±10 V command value.
• 17.90 kg installed weight, NBR seals, HL hydraulic fluid.

Applications

Used in forming plants and test rigs whose return line runs through coolers and fine filters. Where several valves share one return manifold, the dedicated drain line prevents mutual interference. Pilot pressure is tapped directly from P.
