Proportional Directional Valve 4WRZ10W6-85-7X/6EG24N9K4/M - Bosch Rexroth R900963835

4WRZ10W6-85-7X/6EG24N9K4/M receives pilot oil from outside and returns it to the outside. Pilot stage and working line therefore share no line, which keeps metering stable even when system pressure sags. Maximum flow is 170 l/min.

Advantages

• External pilot oil supply and external pilot oil return, a pilot stage with no feedback from the main circuit
• 85 l/min nominal flow, up to 170 l/min maximum flow
• Symbol W6, three switching positions, four ports
• Maximum operating pressure 315 bar, NBR seals, HL hydraulic fluid
• 7.74 kg mass, size 10, subplate mounting
• 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 is used in accumulator-fed plants where system pressure drops noticeably between two charging cycles.
