Proportional Directional Valve 4WRTE25E350L-4X/6EG24EK31/A1M - Bosch Rexroth R901006918

A ±10 V voltage command is the most common analog interface in drive technology. This 4WRTE25 with spool symbol E processes it in its on-board electronics and converts it into a flow of up to 870 l/min, at 350 l/min nominal flow.

Benefits

• Analog ±10 V command value, the standard interface of common machine controls
• 350 l/min nominal flow, 870 l/min maximum flow
• Spool symbol E, three switching positions, four ports
• Internal pilot oil supply, external pilot oil return
• ISO 4401-08-08-0-05 interface, 350 bar, on-board electronics, NBR seals

Applications

Used in presses, lifting gear and test equipment whose controller outputs an analog voltage. Because the valve needs no amplifier card, wiring is reduced to one cable with a 7-pole connector. The external pilot drain keeps counter pressure away from the pilot stage.
