Proportional Directional Valve 4WRZ10E1-25-7X/6EG24N9ETK4/D3M - Bosch Rexroth R900976118

A fine valve in a tight manifold should not demand additional ports. The 4WRZ10E1-25-7X/6EG24N9ETK4/D3M feeds and discharges pilot oil internally while controlling at 25 l/min nominal flow.

Benefits

• 25 l/min nominal flow with internal pilot routing, no additional lines.
• 170 l/min maximum flow, 315 bar operating pressure in size 10.
• Spool symbol E1, 3 switching positions across 4 ports to ISO 4401-05-05-0-05.
• Pressure reducing valve in the pilot stage, concealed auxiliary actuation for emergencies.
• 8.2 kg, 24 VDC, NBR seals, rated for HL hydraulic fluid.

Applications

The application is on small positioning axes in machine tools and handling equipment. The low nominal step allows slow approach without judder. Because both pilot paths run internally, the manifold stays slim and assembly short.
