Proportional Directional Valve 4WRTE27W6-500L-4X/6EG24ETK31/F1M - Bosch Rexroth R900244543

Some plants want neither a second oil line nor a sensitive voltage signal. The 4WRTE27W6-500L-4X/6EG24ETK31/F1M solves both, because pilot oil flows in and out internally while the valve is commanded with 4 to 20 mA at 500 l/min nominal flow.

Benefits

• Internal pilot oil supply and internal return keep the pipework limited to P and T.
• A 4 to 20 mA current command stays stable next to drive converters and long cables.
• Nominal flow 500 l/min, maximum 1000 l/min, at 270 bar operating pressure.
• Spool symbol W6 with 3 switching positions and internal spool position feedback.
• Connection diagram ISO 4401-08-07-0-05 in size 27, 4 ports, weight 19.62 kg.
• NBR seals for HL hydraulic fluid, supply 24 V DC.

Applications

Typical places are recycling presses, scrap shears and lifting axes in dusty surroundings with long cable runs. Since no separate pilot circuit is needed, the valve also runs on simple power units. Position feedback keeps the movement even across the full stroke.
