V-Port Control Valves

Flo-Tite’s Quarter Turn Solution to Control Valves

Control valves are considered the most important element in the control loop.  For many years, the common globe valve was the traditional control element in the process industry.  However, these valves have many drawbacks along with their fine qualities as control valves.  Many important features like shutoff capability, flow capacity, dynamic stability, operating forces, stem leakage, handling of dirty fluid, weight and bulkiness as well as maintenance and cost have led valve manufacturers to seek other solutions for the right valve technology.  Recently, quarter turn ball valves have been applied to many control applications with great success.  The simple ball valve construction along with a new controlling device has introduced to the industrial market a controlling element solution that can be utilized in many applications.  The ball valve has many advantages over the globe valve due to its inherent high flow capacity, floating ball design, seat wiping action and rotary stem.  These together with a new seat technology and modular building of computer linked control elements give the ball valve superiority and cost effective performance in the fast growing world of modern technology.
