Fundamentals

A control valve continuously adjusts the process variable. An isolation valve establishes an open or closed boundary. One assembly can sometimes do both,.

A well-selected V-port valve can be effective in many industrial control duties, but no valve geometry is best for every fluid and pressure profile..

Valve terminology overlaps across manufacturers. Use the trade name to find the product, then use a drawing and a technical datasheet to identify what.

A V-port ball valve uses a characterized opening to vary the available flow passage as the rotating element moves. In a segmented design, the moving.
