Proportional Directional Valve 4WRTE25V1-350P-4X/6EG24K31/A1V - Bosch Rexroth R900950304

In plants that jump between rapid traverse and pressing force the pilot stage has to keep its response time. The 4WRTE25V1-350P-4X/6EG24K31/A1V therefore draws pilot oil from outside and meters 350 l/min nominal flow up to 350 bar.

Benefits

• External pilot oil supply and return - response time stays the same whatever the working pressure does.
• 350 l/min nominal flow in size 25, up to 870 l/min maximum.
• Symbol V1 with fine control range and internal spool position feedback.
• Command value ±10 V on 24 VDC, wired through a 7-pole connector (6 + PE).
• 17.98 kg on the ISO 4401-08-08-0-05 subplate interface, FKM seals for HL fluid.

Application

Valves like this run in deep drawing presses, high tonnage injection moulding machines and hoists with changing loads. A separate pilot circuit stabilises behaviour during the phases with low system pressure. Three switching positions cover both directions and the centre.
