Alfa Laval SB Anti Vacuum ValveThe Alfa Laval SB Anti Vacuum Valve is a hygienic vacuum relief valve designed to protect closed tanks from collapse caused by internal vacuum conditions.
It is commonly used during tank emptying, cooling after hot cleaning, and CO2 caustic cleaning, where vacuum pressure may form inside the tank. This valve automatically allows air into the tank to prevent damage and ensure safe operation.
Suitable for brewery, dairy, food and beverage and other hygienic industries.

How does SB Anti Vacuum Safety Valve work? |
|
|
The valve is equipped with a preset counterweight based on the tank’s vacuum tolerance. When internal pressure drops below the safe level, the valve automatically opens and allows atmospheric air into the tank. This prevents vacuum build-up and protects the tank from implosion |
An anti vacuum valve protects tanks from collapsing by allowing air to enter when vacuum pressure occurs inside the tank.
You need it during processes like tank emptying, cooling after CIP, or CO2 cleaning, where vacuum conditions can form
