Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9TK31/A1D3V - Bosch Rexroth R900951429

A hoist with its own pilot pump puts two conditions on the valve. The 4WRZE10W6-85-7X/6EG24N9TK31/A1D3V meets them through spool symbol W6 and the X port, controls 85 l/min nominal flow and relieves the pilot stage into the T port.

Benefits

• Spool symbol W6 blocks in mid position, so the load stands without an additional holding valve.
• External pilot oil supply through X with internal return through T, only one extra line.
• 85 l/min nominal flow in size 10 at operating pressures up to 315 bar.
• Plus or minus 10 V command at the on-board electronics, integrated pressure reducing valve in the pilot circuit.
• FKM seals, mounting pattern ISO 4401-05-05-0-05, weight 9.14 kg, UKCA conformity.

Applications

Valves of this kind work on hoists, on swivel drives and on feed axes carrying a standing load. The dedicated pilot pump keeps control pressure even when working pressure collapses. 85 l/min nominal flow provides a brisk stroke.
