Proportional Directional Valve 4WRZ10E25-7X/6EG24N9EK4/D3V - Bosch Rexroth R900973229

At 25 l/min nominal flow an axis can be advanced very finely. So that back pressure in the tank gallery does not disturb the pilot stage, the 4WRZ10E25-7X/6EG24N9EK4/D3V routes the pilot return outside while the supply stays internal.

Benefits

• 25 l/min nominal flow at a maximum flow of 170 l/min.
• External pilot return with internal supply, independent of back pressure in the return line.
• Spool symbol E with 3 switching positions across 4 ports.
• 315 bar operating pressure in size 10 to ISO 4401-05-05-0-05.
• 8.24 kg with FKM seals, driven by external electronics on 24 VDC.

Applications

For feed axes on machine tools and test rigs whose return line runs through filter and cooler. The concealed auxiliary actuation helps during commissioning. FKM seals take higher oil temperatures than a standard NBR fit.
