Proportional Directional Valve 4WRTE27V1-500L-4X/6EG24K31/F1M - Bosch Rexroth R901349441

In long cable looms and on a heavily loaded return line, separation pays off. The 4WRTE27V1-500L-4X/6EG24K31/F1M uses a 4...20 mA current setpoint and a pilot circuit that is supplied and drained externally, at 500 l/min nominal flow and 270 bar operating pressure.

Benefits

• 4...20 mA setpoint, tolerant of voltage drop on long cables.
• External pilot oil supply and external pilot oil return, independent of tank pressure.
• 500 l/min nominal flow in size 27, 1000 l/min maximum.
• Spool symbol V1, 3 switching positions, operating pressure up to 270 bar.
• NBR seals, ISO 4401-08-07-0-05 interface, 19.36 kg.

Applications

The valve is used in spread out installations where the control cabinet and the valve are far apart, for example in rolling mills and forming lines. A dedicated pilot circuit at constant pressure is required. The combination keeps the step response equal across the whole load range.
