Descaling systems

Basis for Evertz Hydrotechnik descaling valves and descaling systems constitutes our basic valve program:

  • 2/2 way cartridge valves
  • 2/2 way built check valves
  • Check valve inserts (manual or motorized)
  • Storage completion valve inserts
  • 3/2 way pilot valves


for the following standard operating conditions:

  • Media: Water, water-oil emulsions, synthetic oils, corrosive media, hydraulic oil, compressed air
  • Pressures: Standard 0 to 350 bar (max up to 800 bar)
  • Nominal sizes: DN3 to DN250
  • Temperatures: max. Operating temperature 0 to + 70 ° C; Max. Ambient temperature: 0 to + 60 ° C


Furthermore, a number individually to the particular application developed special valves available:

  • Pressure relief / pressure reducing valves
  • Proportional valves
  • pilot operated check valves
  • and much more


If you have a request outside of our standards, then we will develop a solution for you!

  • Descaling valve, for example, as

    • Single valve (switching valve)
    • Descaling valve unit (switching valve + check valve)
    • Descaling valve unit as a redundant system (see photo)
  • Descaling, e.g. incl.

    • Auto. Width adjustment for different billet widths

    • individually switchable nozzle
  • Memory port valve, for example, as

    • Single valve (switching valve)
    • Memory close valve unit (switching valve + check valve)
  • High-pressure reservoir, e.g. incl.

    • Radar level measurement
  • Pump circulation valve, for example, incl.

    • 2/2 way check valve
    • manual shutoff valve
    • 2/2 way switching valve
    • minimum quantities throttle
  • Other accessories, such as

    • Electrical control
    • High Pressure Pumps
    • Remove station
