Proportional Directional Valve 4WRZ10W8-25-7X/6EG24N9ETK4/M - Bosch Rexroth R901071883

During commissioning the electronics are often not ready while the axis already has to move. This proportional valve has a concealed auxiliary actuation for that. In service it carries a nominal flow of 25 l/min to symbol W8, with 170 l/min allowed at maximum.

Benefits

• Concealed auxiliary actuation for commissioning and fault finding without a control signal
• Nominal flow 25 l/min for slow, finely metered motions
• Symbol W8 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 7.72 kg

Applications

The valve controls infeed and positioning axes in machine tools and test rigs. The concealed auxiliary actuation is useful during maintenance and troubleshooting while staying protected against accidental operation in service.
