Proportional Directional Valve 4WRTE25W8-220L-4X/6EG24TK31/A1M - Bosch Rexroth R900713241

When old manifolds are retrofitted the free drain line is often missing while a dedicated pilot pressure source is already in place. This version is built for exactly that case, with 220 l/min nominal flow at 350 bar in size 25.

Benefits

• External pilot oil supply with internal return, matching manifolds that have an X line but no Y line.
• 220 l/min nominal flow for mid-size cylinders, flow up to 870 l/min possible.
• 350 bar operating pressure, spool symbol W8, 3 switching positions.
• ±10 V command value with internal spool position feedback through the on-board electronics.
• 18 kg installed weight, NBR seals, connection diagram ISO 4401-08-08-0-05.

Applications

Mostly used for replacements in existing presses, clamping systems and lifting gear where the pipework should stay untouched. The pilot circuit is fed from system pressure or from a small dedicated pump. Pilot oil returns to tank together with the main flow.
