K = K value of the total valve
K<sub>1<sub>=Reducing the K value of the seat
β = d<sub>valve</sub> / d<sub>pipe</sub>
K<sub>R</sub> = reduced K value
K<sub>E</sub> = increased k value
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.
Reduce the K value of the seat: 45
Reduced K value: 40
Increased k value: 3
β:10
