Proportional Directional Valve 4WRZ10E50-7X/6EG24N9EK4/M - Bosch Rexroth R900756711

4WRZ10E50-7X/6EG24N9EK4/M combines internal pilot oil supply with external pilot oil return. The pilot circuit works against ambient pressure instead of back pressure in the tank gallery, which keeps the metering curve reproducible.

Advantages

• Internal pilot oil feed with no additional pressure line
• External pilot oil return against low back pressure
• 50 l/min nominal flow, up to 170 l/min maximum flow
• Symbol E, three switching positions, maximum operating pressure 315 bar
• 7.74 kg mass, NBR seals, HL hydraulic fluid
• Electrical with external electronics, concealed auxiliary actuation

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 porting is used on plants with a long return run or a return filter that raises tank pressure noticeably.
