K Value of the Total Valve:
Reduced Seated Valves and Fittings Calculator

The reduced seat valve is broken down into three sections: the reducer (contraction) section, the segmented valve, and the amplifier section.

The K value is related to the size of the valve in the pipe, each segment is determined.

The full K value is the valve's K value of the reducer, the segmented valve, and the amplifier. Since the valve part K value depends on the seat diameter instead of the pipe diameter, it must be adjusted by a correction factor to determine the correct K value of the pipe diameter.

The valve correction factor is the ratio of the seat diameter divided by the pipe diameter (commonly referred to as β) to the fourth power.
