MATERIAL LIST

Product Specifications :

Full port

A full port or more commonly known full bore ball valve has an over-sized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted but the valve is larger and more expensive so this is only used where free flow is required, for example in pipelines which require pigging.

Reduced port

In Reduced port (more commonly known as reduced bore) ball valves, flow through the valve is one pipe size smaller than the valve's pipe size resulting in flow area being smaller than pipe. As the flow discharge remains constant and is equal to area of flow (A) times velocity (V), A_1V_1=A_2V_2 the velocity increases with reduced area of flow.

Ball valves are best used for fast-acting stop/start applications. They are considered quick-acting because they only require a 90° turn of the handle to operate the valve. The quarter turn minimizes valve operation time and decreases the possibility of leakage due to wear. Ball valves are available in a floating ball design and trunnion mounted design.They are widely used in petroleum refining, long-distance pipelines, chemical, paper making , water conservation, electric power, steel industry and other industries.
