The CCI Rotary DRAG axial flow valve claims to combine the elevated capacity found in rotary valves with the precise flow control of a high velocity control valve for the gas transmission market. The system capitalises on the capacity of the rotary design and creates a control valve by employing a series of multiple pressure reducing paths within a portion of the ball. With more than 28 stages of pressure reduction and high flow capacity, the design results in precise low-end flow and noise control; while high capacity is achieved through the relatively unobstructed rotary valve trim.
