Breather valves 

Breather valves are the most suitable tanks or installation protection against exceeding safe set pressure values. Breather valves distinguish on groups, considering their performance:

  • overpressure valves – their task is to lead off an excess of agent outside the tank/installation, preventing the formation of an explosion;
  • underpressure valves – their task is to complement the deficiency of gas inside the tank/installation, preventing the formation of an implosion.

CORONA offers both direction breather valves (operating over- and underpressure), which enables solving both problems at the same time, within one unit. Additional advantage of breather valve employment is possibility of combining them with flame quenchers. It is a convenient solution, as violent explosion also causes pressure changes.
