Tank Pressure and Vacuum Relief Valve is also called breathing valve. The valve is used in pressure vessel piping systems, to ensure the safety of equipment and related instruments.
When the pressure is normal, the valve is closed. If the pressure changes, the spring in the valve is compressed or stretched. If the equipment pressure is higher than the set pressure (standard 1 bar), the valve will automatically open for venting. When a vacuum (standard -0.2 bar) is generated in the piping system, the valve will automatically open for allowing outside air to enter the container, preventing the container from being flattened.
The valve is made of stainless steel and has a hygienic design. It is suitable for various industrial fields such as food processing, beer, beverage, and pharmaceutical.
