Proportional Directional Valve 4WRZ10W6-25-7X/6EG24N9TK4/M - Bosch Rexroth R900977871

4WRZ10W6-25-7X/6EG24N9TK4/M receives its pilot pressure from outside and drains through the valve tank gallery. Nominal flow is 25 l/min, maximum flow 170 l/min and the mass 7.76 kg.

Advantages

• External pilot oil supply, so the pilot stage switches even at low main pressure
• Internal pilot oil return through the valve tank gallery
• 25 l/min nominal flow, up to 170 l/min maximum flow
• Symbol W6 with three switching positions, maximum operating pressure 315 bar
• 7.76 kg mass, NBR seals, HL hydraulic fluid
• Concealed auxiliary actuation, electrical control with external electronics

Technical data

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 suits circuits with accumulator charging where system pressure falls off cyclically.
