Wegeventil 4WRLE27V1-600L-4X/VPY/24F1 - Bosch Rexroth R901540365

Large volume cylinders in presses and test rigs call for a size 27 valve that picks up its command value clearly even over long cable runs. The 4WRLE27V1-600L-4X/VPY/24F1 meters 600 l/min nominal flow at a maximum operating pressure of 270 bar and follows a 4...20 mA current command.

Benefits

• 600 l/min nominal flow at up to 270 bar, with a housing flow limit of 1850 l/min.
• 4...20 mA current command through a 7-pole connector (6 + PE) according to EN 175201-804, 24 VDC supply.
• Internal pilot oil supply with external return through Y, keeping the pilot circuit clear of the main return line.
• Spool symbol V1 with 3 switching positions on 4 ports, mounting pattern ISO 4401-08-08-0-05.
• 20.5 kg installed weight, FKM seals, HL hydraulic fluid, CE conformity.

Technical data

Applications

The layout suits plants with a shared return line through cooler and filter, such as presses, forging equipment and large test rigs. A 4...20 mA signal stays readable over long cable runs and in electrically noisy surroundings. Up to 1850 l/min remains in reserve if the axis is later run faster. FKM seals allow warmer oil temperatures than NBR versions.
