Proportional Directional Valve 4WRZ10E50-7X/6EG24N9ETK4/M - Bosch Rexroth R900959030

4WRZ10E50-7X/6EG24N9ETK4/M draws pilot oil from the P gallery and drains into the tank gallery. The standard mounting face is therefore all that installation needs, while the main spool at 50 l/min nominal flow opens up to 170 l/min.

Advantages

• Internal pilot oil supply and internal pilot oil return, mounted without extra lines
• 50 l/min nominal flow, maximum flow 170 l/min
• Symbol E with three switching positions and stepless metering in between
• Maximum operating pressure 315 bar, size 10, NBR seals
• 7.76 kg mass, HL hydraulic fluid
• Concealed auxiliary actuation, no integrated pressure reducing valve

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 assumes that enough pressure stands in the P gallery throughout the cycle to pilot the valve.
