Using Pipe Reducers with 3-Way Ball Valve Assemblies
TThe following table provides estimated effective Cvs when using a 3-way valve assembly on the same or lager pipe
size. Use these estimated effective Cvs in place of the rated Cvs along with at least 6 valve size diameters of straight
pipe upstream and 3 valve size diameters of straight pipe downstream of the valve body.
WARNING: Do not reduce the valve size to less than one-half the line size, as this may weaken the pipe
reduction area. Physical injury can result if the weakened piping fails.
