Proportional Directional Valve 4WRTE32W8-600L-4X/6EG24TK31/A1M - Bosch Rexroth R900736833

External pilot oil supply with internal pilot oil return saves one line without tying the pilot stage to working pressure. The 4WRTE32W8-600L-4X/6EG24TK31/A1M is built that way and meters up to 600 l/min at 350 bar following a plus or minus 10 V command.

Benefits

• External pilot supply with internal return means only 1 extra pilot line instead of 2.
• Nominal flow of 600 l/min, maximum flow of 1600 l/min, operating pressure up to 350 bar.
• Spool symbol W8 with 3 switching positions across 4 ports to ISO 4401-10-09-0-05.
• Internal spool position feedback keeps metering areas repeatable over the whole plus or minus 10 V command range.
• On-board electronics at 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804, weight 37.22 kg.

Applications

The valve fits presses, plastics machinery and test rigs whose pilot pump runs separately while the tank line stays sufficiently relieved. The internal return noticeably shortens the piping at the subplate. Mineral oil of class HL is intended, sealed with NBR.
