Breather Valve

An enclosed system, such as a tank or a vessel, requires a breather valve, sometimes referred to as a pressure relief valve or a pressure/vacuum valve, to manage the pressure within. Its goal is to maintain the system's integrity and safety by preventing the pressure from rising over safe levels. Breather valves are often employed in a number of different industries, including the chemical, pharmaceutical, manufacturing, and oil and gas sectors. They are essential for preserving the correct pressure balance in machinery or storage tanks, which might fluctuate as a result of a variety of reasons, including temperature changes, fluid movements, or chemical reactions.

A breather valve's main purpose is to release excess pressure that has built up within the system. The valve opens, enabling the excess pressure to be released into the atmosphere when the internal pressure rises over a predefined set threshold. These valves can also work in reverse to stop a vacuum or negative pressure from building up inside the system. The valve opens, enabling outside air to enter and restore the internal pressure when it falls below a certain threshold.
