Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9EK4/D3M - Bosch Rexroth R900706740

Electronics on the valve stand in vibration and heat, in the cabinet they do not. The 4WRZ10E1-85-7X/6EG24N9EK4/D3M therefore works with external electronics while controlling 85 l/min nominal flow in size 10.

Benefits

• Electrical with external electronics, amplifier card centrally in the cabinet, 24 VDC supply.
• 85 l/min nominal flow, 170 l/min maximum at 315 bar operating pressure.
• Internal pilot oil supply, external return of the pilot stage.
• Spool symbol E1, 3 switching positions, 4 ports in size 10.
• 8.24 kg, NBR seals, HL fluid, 7-pole plug (6 + PE) to EN 175201-804.

Applications

The application is on machines whose valve block gets hot or vibrates heavily, for instance presses and forging plant. Separating valve and electronics simplifies replacement during service. The 7-pole plug to EN 175201-804 carries command value, feedback and supply in one cable.
