How Does Breather Valve Work?

25/03/2026

A breather valve is a direct-acting safety device designed to protect storage tanks by automatically relieving excess pressure or admitting air when internal pressure falls below a preset level. It maintains pressure and vacuum balance within the tank, preventing overpressure or vacuum conditions that could cause deformation or damage, while also minimizing evaporation losses during storage.
