Breather Valves or Pressure/Vacuum Relief Valves are designed for providing complete protection to tanks. They are designed to be used with blanketed vessels in which different solvents are flown at a high rate of flow. In addition to this, they can also be installed on the process vessels for providing protection to the process equipment from unpredicted pressure fluctuations. They ensure to provide projection from increased fire by keeping the level of toxic vapors balanced and avoiding the atmospheric contamination. It is ideal to provide protecting to tanks from possible casualty from over pressure developed by the thermal expansion as well as product movement.
