Proportional Directional Valve 4WRTE10W8-100L-4X/6EG24ETK31/F1M - Bosch Rexroth R901039674

Hoists and feed drives with short cycle times need flow capacity while the manifold should stay slim. The 4WRTE10W8-100L-4X/6EG24ETK31/F1M combines a 100 l/min nominal flow with internal pilot oil supply and internal return.

Advantages

• Nominal flow of 100 l/min, up to 170 l/min with the spool fully open.
• Internal piloting in both supply and return, the manifold carries only the four main ports.
• Current command 4...20 mA, stable even over longer runs in a cable duct.
• Operating pressure up to 350 bar, spool symbol W8 with three switching positions.
• On-board electronics with a 7-pole connector (6 + PE) to EN 175201-804.
• Weight of 9.52 kg, NBR seals, HL hydraulic fluid.

Applications

The version fits hoists, drawing equipment and indexing axes with short cycle times. Because both pilot paths run internally, the number of fittings and therefore of leak points stays low. Pilot pressure at port P has to be secured across the entire cycle.
