Proportional Directional Valve 4WRTEM16W6-150L-4X/6EG24ETK31/A1V - Bosch Rexroth R901554107

Too large a nominal flow makes an axis nervous, too small a one slows it down. At 150 l/min this build of the size 16 range sits between the steps while working up to 350 bar with spool symbol W6.

Benefits

• 150 l/min nominal flow, the range itself allows up to 460 l/min maximum flow.
• Same ISO 4401-07-07-0-05 pattern as the 220 l/min variant, so a swap leaves the manifold alone.
• Internal pilot oil supply with internal return, no extra pilot pump required.
• FKM seals at 11.5 kg mass, hydraulic fluid class HL.
• On-board electronics on a ±10 V command value, 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.

Applications

The step suits medium cylinder axes in presses, lifting gear and machine tools. If an existing axis runs too restless, moving from 220 l/min to 150 l/min lowers loop gain without touching the piping. Spool symbol W6 across 3 switching positions stays the same.
