SBV Sanitary Ball Valve

SBV Sanitary Ball ValveConcept

SBV is a sanitary ball valve designed for use as a product valve, in applications within food, beverage, pharmaceutical and chemical industries. The full bore design with zero flow restriction makes SBV the optimum choice for viscous or particulate liquids.

Working principle

A precision made ball with a bore is positioned inside the valve body between two flanges and two PTFE valve seats. A 90° rotation of the valve stem is transferred to the ball and thereby opening or closing the valve. A special selected PTFE material grade secures long lifetime of the product wetted seals. Reliable valve stem sealing is achieved by the use of spring loaded and self adjusting seal rings. SBV is operated by a pneumatic actuator or manually operated by means of a handle with lockable positions. The valve is assembled with screws for easy inspection and maintenance.

Standard Design

The standard actuator is prepared for position indication with inductive proximity switches. The actuator is maintenance free. Two inspection holes in the bonnet connecting valve body and actuator allow for easy inspection of the stem seal tightness. Actuated valves are delivered NC (normally closed) and are easily rebuild to NO (normally open).


How it works


The Alfa Laval SBV sanitary ball valve consists of a valve body, two flanges, PTFE valve seats, ball, stem unit and either a handle for manual operation, or a bonnet and pneumatic actuator for automated operation. For quick and easy inspection and maintenance, the valve easily assembles and disassembles with welded-end flange screws.

Operating principle

A precision-made ball with a bore, or opening, is positioned inside the valve body between two flanges and two PTFE valve seats.
