Single Breather Valve is installed on storage tank, which is used to release inside negative pressure, so that the liquid flows easily. When the liquid flows outside, the tank must inhale air to inside (called “Negative Pressure”). If stop working, the single breather valve will be closed automatically, and the liquid can’t be given away.
