Proportional Directional Valve 4WRZE10W6-85-7X/6EG24K31/A1D3M - Bosch Rexroth R900954651

Lifting gear feeds its pilot pressure from a separate circuit so the load stays controllable during a pressure drop. The 4WRZE10W6-85-7X/6EG24K31/A1D3M is built with external pilot oil supply and external return for that purpose, regulating 85 l/min nominal flow at a maximum operating pressure of 315 bar.

Benefits

• External pilot oil supply and external return keep the pilot pressure alive through load changes.
• Nominal flow 85 l/min, maximum flow 170 l/min, size 10.
• Spool symbol W6, three switching positions, four ports to ISO 4401-05-05-0-05.
• Pressure reducing valve in the pilot circuit, operating pressure up to 315 bar.
• Analog ±10 V command value, 24 VDC supply, 8.45 kg weight.

Applications

Hoists, lock gates and stage drives deliberately run their pilot stage from a separate circuit. The valve bolts onto the size 10 subplate and is powered through the 7-pole connector to EN 175201-804. The ±10 V command value comes from the axis controller.
