Application
SBV is a sanitary ball valve designed for use as a product
valve. The valve is suitable for 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.
SBV is operated by a pneumatic actuator or manually operated by means of a
handle.
Standard Design
SBV consists of a valve body, two flanges, PTFE valve
seats, ball, stem unit and a handle or bonnet and actuator unit. SBV is a
full bore valve with a constant pipeline diameter and a flow restriction
comparable to that of a straight tube. 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.
The standard actuator is prepared for position indication
with inductive proximity switches. A special actuator (option) is designed
for mounting of the Alfa Laval ThinkTop®. 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 rebuilt to NO (normally
open).
The stainless steel handle for manual operation
mechanically locks the valve in open or closed position. The valve is
assembled with screws for easy inspection and maintenance.
