Tapping pilot oil internally at 350 bar system pressure calls for pressure limitation ahead of it. This size 25 valve already carries that pressure reducing valve while metering 220 l/min nominal flow, spool symbol E, command value 4 to 20 mA.

BRR-R978911947

Internal pilot oil pick-off at high system pressure only works if the pilot stage is protected. This pilot-operated proportional directional valve in size 25 has the pressure reducing valve built in, metering 220 l/min nominal flow at 350 bar operating pressure.

Advantages

  • Built-in pressure reducing valve holds pilot pressure independent of system pressure up to 350 bar.
  • 220 l/min nominal flow, with 870 l/min permitted as maximum.
  • Internal pilot oil supply with external return leaves only the Y port to pipe.
  • 4 to 20 mA command value on the on-board electronics, immune to noise over long cables.
  • Concealed auxiliary actuation, FKM seals, 20.58 kg, UKCA evidence.

Applications

Intended for high-pressure circuits lacking a pilot supply of their own, on presses, clamping systems, test rigs. Integrating the pressure reducing valve saves a separate component in the manifold along with one more potential leak point.
