Frequently Bought Together

Back pressure in the tank line shifts the null position of a pilot-operated valve. This version therefore has both its own supply X and its own drain Y, and delivers 325 l/min from a 4...20 mA current command.

Benefits

  • A dedicated pilot drain Y keeps the pilot stage clear of back pressure in the tank line.
  • A dedicated supply X makes control pressure available independently of the working pressure.
  • Nominal flow of 325 l/min with spool symbol W8, maximum flow 870 l/min.
  • Operating pressure up to 350 bar, three switching positions, four ports, NBR seals.
  • Command 4...20 mA into the on-board electronics, 24 VDC, mass 20.3 kg.

Applications

The layout pays off wherever several valves work into a shared tank line and build back pressure there, for example in large manifold assemblies on press lines. The Y line is routed to tank without pressure. Interface pattern ISO 4401-08-08-0-05 corresponds to size 25.
