Proportional Directional Valve 4WRZ10E85-7X/6EG24N9EK4/M - Bosch Rexroth R900732237

4WRZ10E85-7X/6EG24N9EK4/M draws pilot pressure from the P gallery and leads the drain oil away separately. The pilot stage therefore stays clear of back pressure in the return, while the main spool opens up to 170 l/min. The mass is 8.26 kg.

Advantages

• Internal pilot oil supply, external pilot oil return against low back pressure
• 85 l/min nominal flow, maximum flow 170 l/min
• Symbol E with three switching positions and stepless metering
• Maximum operating pressure 315 bar, size 10, NBR seals
• 8.26 kg mass, HL hydraulic fluid
• No integrated pressure reducing valve, 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 build suits axes with a high oil demand in plants whose return line runs through coolers and filters.
