Proportional Directional Valve 4WRTE10W8-50L-4X/6EG24EK31/F1M - Bosch Rexroth R901005995

In foundries, rolling mills and forges, signal lines are rarely short or free of interference. The 4WRTE10W8-50L-4X/6EG24EK31/F1M therefore works on a 4...20 mA current command and meters a 50 l/min nominal flow.

Advantages

• Current command 4...20 mA, transmission stays lossless over long distances.
• Internal pilot oil supply with external return through Y for circuits carrying back pressure.
• Nominal flow of 50 l/min, up to 170 l/min total.
• Operating pressure up to 350 bar, spool symbol W8 with three switching positions.
• Weight of 8.42 kg, NBR seals, HL hydraulic fluid.
• Subplate mounting ISO 4401-05-05-0-05, 7-pole connector (6 + PE) to EN 175201-804.

Applications

It is used in plants with heavy electrical interference and long cable routes. The separate return keeps the pilot circuit clear of the back pressure created by return filters. With an internal supply, the minimum pressure at P has to be maintained across the working cycle.
