Proportional Directional Valve 4WRZ10W6-25-7X/6EG24N9K4/M - Bosch Rexroth R901067262

4WRZ10W6-25-7X/6EG24N9K4/M works with external pilot oil supply and external pilot oil return, so the pilot circuit is completely separate from the main circuit. Nominal flow is 25 l/min and the mass 7.76 kg.

Advantages

• External pilot oil supply and external pilot oil return, a fully separate pilot circuit
• 25 l/min nominal flow for fine metering of small actuators
• Up to 170 l/min maximum flow, maximum operating pressure 315 bar
• Symbol W6 with three switching positions
• 7.76 kg mass, NBR seals, HL hydraulic fluid
• 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. The separate pilot circuit pays off when the main pressure swings hard during the cycle or drops away entirely at times.
