Datum Offset (see Figure 6)
Datum to Full Stroke (see Figure 7)
Subtract “Datum Offset” from “Datum to Full Stroke” for
“Full Stroke Distance”
Valve Standoff Distance (see Figures 8 & 9) (Note if Full
Stroke Distance – 1
″
= Valve Standoff Distance then
ABORT THIS TAP!)
Maximum Stroke (photo 10) (Note if Maximum Stroke is
less than Full Stroke Distance be warned that penetration
of the back of the pipe is possible! Observe Unusable
Stroke Remainder (see Figure 12) to execute this tap
safely!)
Add Valve Standoff Distance to Maximum Stroke then di-
vide result by 2 for Ideal Penetration Distance
Subtract Ideal Penetration Distance from Full Stroke
Distance for Unusable Stroke Remainder. (Figure 12)
