Proportional Directional Valve 4WRZ10W6-85-7X/6EG24N9ETK4/M - Bosch Rexroth R900970193

4WRZ10W6-85-7X/6EG24N9ETK4/M takes pilot pressure from the P gallery and drains into the tank gallery. Both pilot lines are therefore dropped at installation, while the main spool with symbol W6 opens up to 170 l/min.

Advantages

• Internal pilot oil supply and internal pilot oil return, installed without separate pilot lines
• 85 l/min nominal flow at up to 170 l/min flow
• Symbol W6, three switching positions, four ports
• Maximum operating pressure 315 bar, size 10, NBR seals
• 7.72 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 precondition is a sufficiently high pressure in the P gallery throughout the cycle so the pilot stage works reliably.
