Proportional Directional Valve 4WRZ10W6-85-7X/6EG24N9EK4/M - Bosch Rexroth R900709133

4WRZ10W6-85-7X/6EG24N9EK4/M combines the 85 l/min nominal stage with an internal pilot feed and an external drain. Symbol W6 sets the behaviour of the main spool, which opens up to 170 l/min.

Advantages

• 85 l/min nominal flow, maximum flow 170 l/min
• Internal pilot oil supply, so no additional pressure line
• External pilot oil return against low back pressure
• Symbol W6, three switching positions, maximum operating pressure 315 bar
• 7.76 kg mass, NBR seals, size 10
• Concealed auxiliary actuation, driven at 24 VDC by external electronics

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. It is used in multi-axis valve manifolds whose shared return line builds back pressure in service.
