Inertization with the original ZIMMERLI valves

Inertization, gassing, blanketing

These low pressure regulators are applied in all places where blanketing of gases, e.g. nitrogen in tanks, plants, reaction vessels or receivers is needed. These IDAG pressure regulators operate in the mbar range and are used in the system. Input and output regulators are adjusted in such a way that a minimum amount of inert gas is used.


  • Reduced inert gas consumption
  • Reduced exhaust gases
  • No external power needed
  • High control accuracy
  • Low maintenance costs
  • Low investment costs
  • No pulse lines needed
