Proportional Directional Valve 4WRTE25V1-350L-4X/6EG24K31/A1M - Bosch Rexroth R900972022

When the controller supplies a voltage signal and the pilot circuit is already built separately, this combination of ±10 V command value and external pilot routing fits. Nominal flow 350 l/min, operating pressure 350 bar.

Benefits

• Command value ±10 V without a signal converter, V1 spool
• External pilot oil supply and external return for a self-contained pilot circuit
• Nominal flow 350 l/min, up to 870 l/min through the valve
• Internal spool position feedback rather than open-loop control
• Operating pressure 350 bar, three switching positions, four ports
• Weight 17.9 kg, port pattern ISO 4401-08-08-0-05

Application

The variant controls axes in roll gap adjustment, servo presses and test rigs with a central pilot supply. Because the pilot circuit stays separate, its pressure can be set independently. HL is the intended hydraulic fluid, sealed with NBR at 24 VDC.
