Cv Value For Ball Valve. Each valve has its own flow coefficient. This depends on how the valve has been designed to let the flow going through the valve.
As the stem opens, the cv increases. Has been contributed to offer high quality product to the global market. There are different types of designs in the ball valve family.
The valve flow coefficient, cv, is the number of u.s.
The valve's flow coefficient, cv, is a value that is determined by flow testing for each valve size. This is used as a guide and is not a linear progression. The valve flow coefficient, cv, is the number of u.s. Full port valves will have a higher cv than reduced port valves.
