Proportional Directional Valve 4WRTE25V350P-4X/6EG24EK31/A1M - Bosch Rexroth R900617664

High or pulsating tank back pressure distorts pilot control when pilot oil drains into the working return. The 4WRTE25V350P-4X/6EG24EK31/A1M avoids that through external pilot oil return while still drawing internal pilot oil supply, at 350 l/min nominal flow and 350 bar.

Benefits

• External pilot oil return drains pilot oil without back pressure and keeps response time stable.
• Internal pilot oil supply saves an extra feed line to the valve.
• 350 l/min nominal flow and up to 870 l/min maximum flow in size 25.
• Analog ±10 V command processed by on-board electronics with spool position feedback.
• Spool symbol V, three switching positions, four ports, mass 17.96 kg.

Applications

Sensible in systems with a shared return line, return filters or coolers that build noticeable back pressure. The characteristic curve stays repeatable even with long return lines. Mounting pattern ISO 4401-08-08-0-05, HL hydraulic fluid.
