Proportional Directional Valve 4WRZ10W6-85-7X/6EG24N9TK4/M - Bosch Rexroth R900971474

4WRZ10W6-85-7X/6EG24N9TK4/M combines the 85 l/min nominal stage with external pilot oil supply and internal return. Pilot pressure therefore stays constant without needing a second return line. Maximum flow is 170 l/min.

Advantages

• 85 l/min nominal flow, up to 170 l/min maximum flow
• External pilot oil supply for constant pilot pressure
• Internal pilot oil return, so no second return line is needed
• Symbol W6 with three switching positions, maximum operating pressure 315 bar
• 7.76 kg mass, NBR seals, HL hydraulic fluid
• Concealed auxiliary actuation, driven by external electronics at 24 VDC

Application

Pilot-operated proportional directional valve in size 10 to connection diagram ISO 4401-05-05-0-05. Control is handled by external amplifier electronics at 24 VDC and the power connector is a 7-pole (6 + PE) type to EN 175201-804. The build is used on hoists and feed drives where the axis accelerates and brakes large masses under control.
