Physical characteristics

  • The main valve is a hydraulically operating diaphragm valve. The work energy is the inherent medium.
  • Most valve types operate purely hydraulically without any foreign energy.

Application

  • To use in drinking water systems (other media after consultation)
  • Sustaining the network pressure in a supply and preventing any backflow
  • Protection of the network by releasing excess pressure, when the backflow also has to be simultaneously prevented
