Control Valve

IMI CCI designed, built and patented the world’s first multi-stage control valve in 1967 as DRAG® technology. For more than 50 years our team has worked with industry professionals across the world, in a wide range of applications, to refine the designs and establish sound engineering rules for velocity control.

This application insight led to the industry accepting guidelines on velocity and fluid kinetic energy control and creating multi-stage design principles that many companies follow today.
