Proportional Directional Valve 4WRTE25V350P-4X/6EG24K31/F1M - Bosch Rexroth R901055213

In plants with a separate pilot circuit the main valve should neither draw from P nor drain into the working return. The 4WRTE25V350P-4X/6EG24K31/F1M is built with external pilot oil supply and external pilot oil return for that reason, handling 350 l/min at 350 bar.

Benefits

• External pilot oil supply and external pilot oil return separate the pilot circuit fully from the working circuit.
• 350 l/min nominal flow, 870 l/min maximum, for cylinders with a large volume demand.
• Command as a 4 ... 20 mA current signal, robust around frequency converters.
• Internal spool position feedback keeps characteristic curves repeatable over service life.
• Standard mounting pattern ISO 4401-08-08-0-05 at a valve mass of 17.85 kg.

Applications

Intended for large presses and test rigs with a dedicated pilot oil supply, and for circuits with high or pulsating tank back pressure. The separated pilot circuit keeps response time independent of working pressure. NBR seals, HL hydraulic fluid.
