DOUBLE OFFSET BUTTERFLY VALVES BEHAVIOUR
TO BEGIN WITH: When it comes to the safety of other components like boilers, reactors, pumps etc., valves play an important role. In many shut-off applications, butterfly valves are the primary selection because of its quarter-turn operation, compact design, and simplicity, one of the primary reasons why many valve suppliers prefer these valves to customers with specific industrial needs. Butterfly valves control fluid flow in a pipe by using a disc attached to a central shaft. This disc controls the amount of fluid passing through the valve by creating a variable opening. These valves can be classified according to the alignment of the disc with respect to the valve body: Zero offset or concentric butterfly valve Double offset butterfly valve Triple offset butterfly valve Majority of butterfly valves with plastic linings are zero offset. Those that are made of metal and some with rubber lining are either double or triple offset butterfly valves. DOUBLE OFFSET VA
