Proportional Directional Valve 4WRZ10E25-7X/6EG24K4/D3M - Bosch Rexroth R900759583

With fine metering, disturbances in the pilot circuit weigh especially heavily. This valve therefore combines a nominal flow of only 25 l/min with external pilot oil supply and external pilot oil return. The main spool follows symbol E, and 170 l/min are allowed at maximum.

Benefits

• Nominal flow 25 l/min for slow and finely metered motions
• External pilot oil supply and external pilot oil return
• Pressure reducing valve in the pilot stage for constant pilot pressure
• Symbol E in 3 switching positions across 4 ports
• Maximum flow 170 l/min, operating pressure up to 315 bar
• NBR seals, subplate mounting to ISO 4401-05-05-0-05, mass 8.24 kg

Applications

The valve controls infeed axes and test cylinders in plants whose tank line is under pressure. The small rating and the stable pilot pressure together give behaviour that repeats well.
