Proportional Directional Valve 4WRZ10E25-7X/6EG24ETK4/D3M - Bosch Rexroth R900977756

The smaller the nominal flow, the more finely an axis can be guided. At 25 l/min this size 10 valve is laid out for slow infeed and positioning motions. The built in pressure reducing section keeps the pilot stage at constant pressure, and 170 l/min are possible at maximum.

Benefits

• Nominal flow 25 l/min for slow and closely guided motions
• Pressure reducing valve in the pilot stage, giving consistent behaviour across the pressure range
• Symbol E in 3 switching positions across 4 ports
• Internal pilot oil supply and internal pilot oil return
• Maximum flow 170 l/min at an operating pressure of up to 315 bar
• NBR seals, subplate mounting to ISO 4401-05-05-0-05, mass 8.22 kg

Applications

Typical duty is on infeed axes, test cylinders and handling drives that should start smoothly and hold position accurately. The small rating spreads the command range across a narrow flow.
