The Alfa Laval Sanitary Ball Valve (SBV) is a hygienic ball valve designed with a bore diameter the same size as the pipeline diameter. The full-bore design with zero flow restriction and minimum pressure drop makes the SBV the optimum choice to handle high-viscosity or particulate liquids. It is also ideal for use in pigging systems to prevent product waste and optimize plant performance.
The Alfa Laval SBV is ideal for use as a hygienic product valve across the dairy, food, beverage, brewery, chemical and many other industries.
Benefits:
- Reliable full-flow performance, especially for pigging systems
- Compact, straightforward hygienic design
- Versatile operation with automated or manual control
- Durable and water hammer-safe
- Easy to clean (optional cavity filler or cavity cleaning)
Standard design
TheAlfaLavalsanitary ball valve consists of a valve body and two
.body flanges, a ball fitting into sealing seats, and a stem connecting to either a pneumatic actuator or a manual handle. The actuator is maintenance-free and prepared for position indication with inductive proximity switches.
The valve can also be fitted with the Alfa Laval ThinkTop® V50 valve sensing and control unit. Two inspection holes in the bonnet connecting the valve body and actuator enable easy inspection of the stem seal for tightness.
Standard design enables cleaning and product recovery using pigging systems. Actuatedvalvesare deliverednormallyclosed(NC)andcan easily be rebuilt to normally open (NO). To optimize valve cleaning, an optional cavity filler or cavity cleaning is available.

Working principle
The Alfa Laval SBV sanitary ball valve has a precision-made ball with full bore positioned inside the valve body between two flanges and two PTFE valve seats. A 90° rotation of the valve stem enables opening or closing the valve. A specially selected PTFE-grade material secures long lifetime. The use of spring-loaded, self-adjusting seal rings ensures the reliability of the valve stem sealing. Either a pneumatic actuator or a manually-operated handle with lockable positions enables valve operation. Valve screws enable assembly and disassembly for easy inspection and maintenance.
