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