INOXPA Pressure-Vacuum Valve 7550

Application

Pressure-vacuum valve is a valve designed to maintain atmospheric pressure inside the tank while it is being filled or emptied. It is widely used in the food-processing, wine-making, cosmetics and chemical industries as well as in the beverage and oil production.

Operating principle

The pressure-vacuum valve is designed to breathe in while the tank is being emptied to equal the pressure inside and outside the tank and protect the tank from vacuum. When the tank is being filled, the valve allows air to come out, thus avoiding excess pressure inside the tank which would cause the tank to swell.
