Proportional Directional Valve 4WRZ10W6-50-7X/6EG24N9EK4/D3V - Bosch Rexroth R900977347

A return line under back pressure must not load the pilot stage. On the 4WRZ10W6-50-7X/6EG24N9EK4/D3V the pilot oil is therefore led away externally while the supply stays internal. Nominal flow is 50 l/min at a maximum of 170 l/min.

Benefits

• 50 l/min nominal flow at a maximum flow of 170 l/min.
• External pilot return with internal supply, independent of back pressure in the tank.
• Spool symbol W6 with 3 switching positions across 4 ports.
• 315 bar operating pressure in size 10 to ISO 4401-05-05-0-05.
• 8.2 kg with FKM seals, driven by external electronics on 24 VDC.

Applications

Fits feed and lift axes on power units whose return line runs through filter and cooler. The concealed auxiliary actuation allows moving the axis during commissioning without power.
