Proportional Directional Valve 4WRTE10W8-50L-4X/6EG24ETK31/F1V - Bosch Rexroth R901449293

An axis at 50 l/min has to be controlled linearly, and the manifold has no room for pilot lines. The 4WRTE10W8-50L-4X/6EG24ETK31/F1V solves both, because pilot supply and return run internally and the characteristic stays linear across the whole command range, at up to 350 bar.

Benefits

• Size 10 with spool symbol W8, rated at 50 l/min nominal flow.
• Pilot oil is taken internally and returned internally, so no separate X and Y line is needed.
• Spool position control works with internal feedback, and the characteristic curve is linear. Operating pressure reaches 350 bar.
• Command value input 4...20 mA on the on-board electronics, wired through a 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC.
• FKM seals, HL fluid, mounting pattern ISO 4401-05-05-0-05, maximum flow 170 l/min, 9.5 kg weight.

Applications

Applications are clamping axes, tracking drives and test cylinders in plants running warm oil. The internal pilot stage saves two lines and simplifies the manifold. With the 4...20 mA command the controller detects a broken wire from the missing rest value.
