Our automatic shut-off valves function is general cut of thermal installations.

 

Automatic closing of this set is done in following cases:

  • Emergency stop local or remote (since the control room)
  • Gas underpressure
  • Gas overpressure

  • Gaseous fuel such as:
  1. Natural gas

  3. Butane
