Tri Clamp air pressure relief valve-SS304
We polished the drilling hole,more smooth
Pressure relief valves, as the name suggests, relieve interior tank pressure when it rises above the 14.7 PSI (1 atmosphere) or other. Used for low pressure system. A pressure vacuum valve prevents the interior pressure from going below -1.5 PSI and thus potentially imploding the tank. Situations where this may occur is during a quick cool down, such as after a cleaning process, or when draining quickly. For protection of tanks against over-pressure or vacuum.
