Proportional Directional Valve 4WRZE10E1-85-7X/6EG24N9TK31/F1M - Bosch Rexroth R901140328

Turbine and valve hydraulics often draw pilot oil from a filtered bypass line while the return stays inside the manifold. The 4WRZE10E1-85-7X/6EG24N9TK31/F1M is built exactly that way and regulates 85 l/min nominal flow through spool symbol E1 up to 315 bar operating pressure.

Benefits

• External pilot oil supply combined with internal pilot oil return.
• Nominal flow 85 l/min, maximum flow 170 l/min, size 10.
• Spool symbol E1 with three switching positions, connection diagram ISO 4401-05-05-0-05.
• Version without pressure reducing valve, concealed auxiliary actuation on the pilot valve.
• Current command 4...20 mA, 24 VDC supply, weight 8.48 kg.

Applications

Power plant actuators, turbine governors and shut-off devices in pipeline systems use a separate, finely filtered pilot supply. The internal return saves the second line back to tank. The electronics in the valve process the current command directly and drive the output stage.
