Introduction to Ball Valve - The ... - The Process Piping
Introduction to Ball Valve A ball valve is a form of quarter-turn shut-off valve that controls the flow of a liquid or gas by means of a rotary ball with a hole bored through the center and sandwiched between two seats. Ball valves do not use a hand-wheel but instead use a wrench handle to control the flow.

Globe valve - Wikipedia
A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body.. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.This has an opening that forms a seat onto which a …
