Proportional Directional Valve 4WRZE16W9-180-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901432538

When pressure rises in the tank line, an internally drained pilot stage changes its behaviour. This version of the 4WRZE16W9 therefore drains the pilot oil externally while the supply stays internal. Nominal flow 180 l/min, maximum flow 460 l/min, spool symbol W9.

Benefits

• Internal pilot oil supply with external pilot oil return for a pilot circuit free of back pressure
• 180 l/min nominal flow, 460 l/min maximum flow, 350 bar operating pressure
• Pressure reducing valve in the pilot circuit and concealed auxiliary actuation
• On-board electronics with analog ±10 V command value at 24 VDC
• ISO 4401-07-07-0-05 interface, NBR seals, UKCA conformity

Applications

Sensible wherever several consumers work into a shared return line and build up pressure there, for example on power units with return filters and coolers. The external pilot drain decouples the pilot stage from that. The valve replaces comparable size 16 types on the ISO 4401-07-07-0-05 interface.
