Rotate the adjustment screw clockwise until the top of the spring block
nut is aligned with the machined portion of the adjustment screw
(Figure 5.19)

nut remains loose for valve testing).
Once the spring block location has been set at the location previously described,
the valve has to undergo a dwell period before testing in order for the seal to
acclimate to the seat. Valves should be kept in a climate-controlled environment
for the full duration of the dwell interval, which is specified by valve type in
Figure
