Proportional Directional Valve 4WRTE16V1-150L-4X/6EG24TK31/F1M - Bosch Rexroth R901567693

A dedicated pilot circuit delivers clean and pressure-stable oil to the pilot stage, while the return may take the internal path. This build of the 4WRTE16V1-150L-4X is connected that way and meters 150 l/min nominal flow at up to 350 bar.

Benefits

• External pilot oil supply with internal return, matched to power units with a separate pilot pump.
• Spool symbol V1 for cylinders with unequal piston areas, three switching positions.
• Internal spool position feedback keeps the characteristic curve stable over service life.
• A 4...20 mA command into on-board electronics, 24 VDC supply at a 7-pole connector (6 + PE) to EN 175201-804.
• 150 l/min nominal flow, mounting pattern ISO 4401-07-07-0-05, weight 11.08 kg.

Applications

Valves of this kind work on test benches, forming machines and lifting axes where the pilot circuit is kept filtered and cooled. Because the pilot stage is fed from outside, it stays fully effective even at low working pressure. NBR seals match mineral oil of class HL.
