Proportional Directional Valve 4WRZE10E25-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901452102

When an axis has to stay movable without control voltage, the concealed auxiliary actuation of the 4WRZE10E25-7X/6EG24N9EK31/F1D3M helps. In normal operation the 4...20 mA current command value drives the spool of symbol E, at 25 l/min nominal flow and up to 315 bar operating pressure. Pilot oil arrives internally and is drained externally.
