Force pilot operated solenoid valve VZWF

Works without differential pressure even in closed media circuits

Controls high pressures at large nominal sizes with small solenoids

  • Switches even at 0 bar
  • Integrated N/C function closes automatically on pressure drops
  • For gaseous and liquid media to max. 22 mm²/s viscosity
  • For water, air and neutral media
  • For filling systems (secondary circuit ), water treatment, heating circuits
