Proportional Directional Valve 4WRZ10E25-7X/6EG24N9K4/M - Bosch Rexroth R900973404

4WRZ10E25-7X/6EG24N9K4/M supplies and returns pilot oil externally. The pilot circuit therefore sits entirely apart from the working line while the main spool sets actuator speed at 25 l/min nominal flow.

Advantages

• 25 l/min nominal flow for small actuators and fine speed setting
• External pilot oil supply and external pilot oil return
• Symbol E, three switching positions, maximum flow 170 l/min
• Maximum operating pressure 315 bar, size 10, NBR seals
• 7.8 kg mass, 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 build is used on positioning and swing axes whose motion has to start and stop without jerk.
