High Flow MultiDirectional Ball Valves (Hoke, Inc.) Zycon from www.zycon.com

As the ball is rotated, in the fully open position the valve provides the through conduit or full bore required for unrestricted flow of the fluid and scrapers or pigs. Ball valves do not have this jump effect. A full bore ball valve has a low flow resistance (high flow coefficient), about the same as a straight piece of pipe.

Ball valves and gate valves are both designed to restrict and control flow. Similar to butterfly valves, they are not as effective for flow control applications that require a high degree of accuracy and. Flow disruptions and fluctuations—valves are in place to keep the flow of the gas or fluid constant and consistent.

Rotation Is Slow, Rack And Pinion Linkage Is Used, The Tendency Of Flow Is To Close A Ball, And A High Seal Resistance, All Contribute To Smooth Rotation Without Jumps, Resulting In Turndown Ratios From 160:1 To 400:1, Depending On Quality Of Actuators, Valves, And Signal.
