Proportional Directional Valve 4WRZ10E85-7X/6EG24N9K4/M - Bosch Rexroth R900969686

4WRZ10E85-7X/6EG24N9K4/M draws pilot oil externally and returns it externally. Pilot pressure and working pressure are thereby decoupled, which supports repeatability of the metering under changing load. Nominal flow is 85 l/min.

Advantages

• External pilot oil supply and external pilot oil return, a fully separate pilot circuit
• 85 l/min nominal flow, maximum flow 170 l/min
• Symbol E with three switching positions and stepless metering
• Maximum operating pressure 315 bar, NBR seals, HL hydraulic fluid
• 7.74 kg mass in size 10
• 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. It is used on presses and test rigs where system pressure jumps noticeably between rapid traverse and force build-up.
