Proportional Directional Valve 4WRZE10E25-7X/6EG24K31/A1D3M - Bosch Rexroth R901056851

Small cylinders on clamping fixtures need fine resolution rather than a large oil volume, otherwise every change of command value turns into a jolt. The 4WRZE10E25-7X/6EG24K31/A1D3M therefore limits nominal flow to 25 l/min while keeping the size 10 frame rated for 315 bar operating pressure.

Benefits

• Nominal flow 25 l/min for sensitive motion, the frame itself releases up to 170 l/min.
• Operating pressure up to 315 bar across four ports to ISO 4401-05-05-0-05.
• External pilot oil supply and external return, plus a pressure reducing valve in the pilot line.
• Analog ±10 V command value, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol E, three switching positions, 8.48 kg weight, NBR seals.

Applications

The small nominal flow suits clamping axes, positioning axes, tool adjustment drives and secondary axes of large machines. On the manifold the valve occupies the same port pattern as the higher-flow frames of size 10. Changing within the series therefore leaves the pipework untouched.
