Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9K4/D3M - Bosch Rexroth R900968393

The pilot pressure decides how quickly the main spool follows. On the 4WRZ10E1-85-7X/6EG24N9K4/D3M it comes from a dedicated source, independent of the main circuit, at 85 l/min nominal flow in size 10.

Benefits

• External pilot oil supply and external return, steady pilot pressure regardless of the main circuit.
• 85 l/min nominal flow, 170 l/min maximum at 315 bar operating pressure.
• Spool symbol E1 with 3 switching positions, 4 ports in size 10.
• Pressure reducing valve in the pilot stage for a defined pilot pressure.
• 8.2 kg, 24 VDC, external electronics, 7-pole plug (6 + PE) to EN 175201-804.

Applications

This combination is wanted on axes whose system pressure swings widely during the cycle, for example on presses with a pressure holding phase. The separate pilot circuit gives the same step response across the whole cycle. The large nominal step allows fast travel without throttling losses in the valve.
