Pressure relief valves, as the name suggests, relieve interior tank pressure when it rises above the 14.7 PSI (1 atmosphere). Our tanks are warrantied as a 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.
