Proportional Directional Valve 4WRTE25V1-350L-4X/6EG24ETK31/F1M - Bosch Rexroth R901355848

High throughput and controlled position are not mutually exclusive here, since this valve combines 350 l/min nominal flow with internal spool position feedback. Pilot oil is both supplied and returned internally.

Benefits

• Nominal flow 350 l/min with closed-loop spool position rather than open-loop control
• Fully internal pilot oil routing, no extra piping on the manifold
• Command value 4...20 mA, a broken wire is detected at zero current
• Operating pressure 350 bar, up to 870 l/min through the valve
• V1 spool, three switching positions, four ports
• Weight 17.8 kg, 24 VDC supply through a 7-pole (6 + PE) connector

Application

The valve is intended for servo presses, forging manipulators and test rigs with large cylinders. Internal pilot routing keeps the manifold compact. HL is the intended hydraulic fluid and the seals are NBR.
