The Alfa Laval SB Pressure Relief Valve is a hygienic safety valve engineered to release excess liquid caused by overpressure in process tanks or vessels due to overfilling. When the internal pressure surpasses a preset threshold, the valve opens to vent the fluid and automatically closes once the pressure drops below the set point. This prevents damage to the tank and ensures safe operation. This safety valve is designed for use in hygienic processes in
the brewery, dairy, food, beverage and many other industries, the valve can be integrated as part of a SCANDI BREW® tank top system.

How does SB Pressure Relief Valve work? |
|
The preset opening pressure must be set at a value that is above the tank working pressure: 0.1 bar above for working pressures <1 bar, and 10% above for working pressures ≥ 1 bar. The valve should be installed horizontally; however, a maximum inclination of 10° is acceptable, but the lever arm must then point inward toward the centre of the cylindroconical tank top. |
