Proportional Directional Valve 4WRTE16E1-150P-4X/6EG24K31/A1M - Bosch Rexroth R901561170

Keeping an existing axis controller means the valve has to match its output. This build of the 4WRTE16E1-150P-4X works from a plus or minus 10 V command and converts it into 150 l/min nominal flow at operating pressures to 350 bar.

Benefits

• A plus or minus 10 V command fits common axis controllers and analogue outputs directly.
• Internal spool position feedback produces a repeatable characteristic curve.
• 150 l/min nominal flow against a range maximum flow of 460 l/min.
• Spool symbol E1, three switching positions, four ports, subplate mounting to ISO 4401-07-07-0-05.
• External pilot oil routing in both directions, weight 11.3 kg, NBR seals.

Applications

Applications include positioning axes in machine tool building, force control on presses and test cylinders. Because the electronics sit inside the valve, a separate amplifier card is unnecessary. The pilot circuit is fed and relieved externally and so stays independent of working pressure.
