Pressure-vacuum valve is a valve designed to maintain atmosphericpressure inside the tank while it is being filled or emptied.
It is widely used in the food-processing, wine-making, cosmetics ,chemical , beverage and oil production.
The pressure-vacuum valve is designed to breathe in while the tank isbeing emptied to equal the pressure inside and outside
the tank andprotect the tank from vacuum. When the tank is being filled, the valveallows air to come out,
thus avoiding excess pressure inside the tankwhich would cause the tank to swell.
