Proportional Directional Valve 4WRZ10W6-25-7X/6EG24N9EK4/M - Bosch Rexroth R900965695

4WRZ10W6-25-7X/6EG24N9EK4/M takes pilot pressure from the P gallery and leads the drain oil away through a line of its own. That keeps the pilot stage clear of back pressure in the tank gallery while the main spool meters 25 l/min nominal flow.

Advantages

• Internal pilot oil supply, so no additional pressure line
• External pilot oil return, independent of back pressure in the tank gallery
• 25 l/min nominal flow, maximum flow 170 l/min
• Symbol W6 with three switching positions, maximum operating pressure 315 bar
• 7.74 kg mass, NBR seals, size 10
• Concealed auxiliary actuation, electrical control with external electronics

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 makes sense when filters, coolers or long return runs raise the tank pressure.
