The V-AXX valve has the highest Kv / Cv of any comparable torque-seated, butterfly valve. How important is a higher Ku / Cv value? In new construction, when the higher Kv / Cv of the V-AXX is considered, the size of the valve can be reduced, minimizing the costs of the valve. But that is just the start. It’s lower torque (combination of the smaller valve size, but also the completely friction free sealing design) allows for a smaller, less costly automation package. Then, with the smaller valve, the piping, and the associated supports are also smaller and less costly.

In new construction, something once thought insignificant, Kv / Cv values, can have a huge impact on the total costs of the investment if You are able to use for example DN 350 instead of DN500. With regards to day to day valve replacement where the pipe size and infrastructure have already been determined, the higher flow coefficients with the V-AXX valve, can improve process performance and lower pumping costs due to the lower pressure drop across the valve.
