Calculate the insertion distance:
For flanged Seal Housing models
MID
–
Minimum Insertion Distance
D1
–
Distance from the top of the valve to the pipe
Lg
–
Gasket Width (Typical 0.134")
WT
–
Pipe Wall Thickness
Ls
–
Pipe ID x 0.25 (Measurement Area Length)
Ds
–
Pipe ID x 0.5 (Measurement Diameter Area)
Minimum Insertion Distance (MID)=D1 + Lg + WT + Ls + LRW Factor
Example: D1=14"
Lg=0.134"
WT=0.25"
ID=8.125"
LRW Factor 2" 150#=1"
MID=14 + 0.134 + 0.25 + (8.125 x 0.25) + 1
MID=17.41"
Take note of the calculated MID and proceed to step 7.
