Proportional Directional Valve 4WRZ10W8-50-7X/6EG24N9EK4/M - Bosch Rexroth R900972500

The pilot circuit of this valve draws its oil from the main circuit and returns it through a separate port. At a nominal flow of 50 l/min, axes of medium speed can be guided, and 170 l/min at 315 bar are allowed at maximum.

Benefits

• Internal pilot oil supply with external pilot oil return, independent of return line pressure
• Nominal flow 50 l/min, maximum flow 170 l/min
• Symbol W8 in 3 switching positions across 4 ports
• Concealed auxiliary actuation for commissioning and fault finding
• Operating pressure up to 315 bar, subplate mounting to ISO 4401-05-05-0-05
• NBR seals for HL hydraulic fluid, mass 7.8 kg

Applications

The valve works on feed and infeed axes in plants whose tank line is under pressure. The command signal comes from external electronics whose ramps can be matched to the motion.
