Proportional Directional Valve 4WRTE27W6-500L-4X/6EG24K31/F1M - Bosch Rexroth R901349445

In steel plants many metres of cable sit between cabinet and valve, and a voltage signal picks up noise along the way. The 4WRTE27W6-500L-4X/6EG24K31/F1M works with a 4 to 20 mA current command instead and controls 500 l/min nominal flow at 270 bar operating pressure.

Benefits

• A 4 to 20 mA current command stays immune over long cables, unlike a voltage signal.
• External pilot oil supply and external return keep the pilot stage separate from the working circuit.
• Nominal flow 500 l/min, maximum 1000 l/min, covers large cylinders in size 27.
• Spool symbol W6 with 3 switching positions and internal spool position feedback.
• Connection diagram ISO 4401-08-07-0-05, 4 ports, NBR seals, weight 19.5 kg.
• Supply 24 V DC through a 7-pole connector (6 + PE) according to EN 175201-804.

Technical data

Applications

The valve positions screw-down cylinders on rolling stands, swing drives on manipulators and lifting axes in metallurgical plants. The current command allows a long distance between control room and power unit. Both pilot oil paths run outside, so the pilot stage can use its own circuit.
