Proportional Directional Valve 4WRZ10E25-7X/6EG24N9EK4/M - Bosch Rexroth R901046289

4WRZ10E25-7X/6EG24N9EK4/M combines an internal pilot oil supply with an external pilot oil return. The pilot stage therefore drains into a line of its own, independent of return pressure in the main gallery, at 25 l/min nominal flow with symbol E.

Advantages

• Internal pilot oil supply, so no additional pressure line is required
• External pilot oil return, decoupling the pilot circuit from back pressure in the tank gallery
• 25 l/min nominal flow, up to 170 l/min maximum flow
• Symbol E, three switching positions, maximum operating pressure 315 bar
• 7.74 kg mass, NBR seals, no integrated pressure reducing valve
• Electrical control with external electronics, 24 VDC

Application

Pilot-operated proportional directional valve in size 10 to connection diagram ISO 4401-05-05-0-05. Control is handled by external amplifier electronics at 24 VDC and the power connector is a 7-pole (6 + PE) type to EN 175201-804. The version makes sense wherever filters or coolers in the return line build noticeable back pressure.
