With raised tank pressure the pilot oil belongs in a separate drain. This build of the 4WRZE16W8-180-7X drains it externally, is driven by 4...20 mA and carries 180 l/min nominal flow at 350 bar operating pressure.

BRR-R901403919

When the return line is under pressure, it falsifies the pilot stage of a directional valve. This build of the 4WRZE16W8-180-7X therefore drains pilot oil externally, takes its command value as 4...20 mA and provides 180 l/min nominal flow at up to 350 bar.

Benefits

  • External pilot oil return keeps the pilot stage independent of back pressure in the tank line.
  • 180 l/min nominal flow and 460 l/min maximum flow in size 16.
  • Internal pilot oil supply saves an extra pressure line to the valve block.
  • A 4...20 mA current command value with on-board electronics on a 24 VDC supply.
  • A pressure reducing valve inside the body provides steady pilot pressure.
  • 12.21 kg mass, FKM seals and UKCA marking under SI2016/1091.

Application

The version makes sense wherever several valves work into a shared return that builds noticeable back pressure. Common places are press blocks and test rig manifolds. Concealed auxiliary actuation remains reachable for service work.
