3. Place the floating flange and hand thread one bolt in the valve body. Place the flange sandwich plate between the valve
seal and the flange seal. Add the rest of the bolts and only hand tighten. Center the sandwich plate using a ruler or a tool
with marking of the correct distance between the ring and outer diameter of the flange (SEE Figure 4). Failure to center
the ring correctly can cause a leak.
4. Rotate the valve assembly to a desired angle or to the suggested orientation in the assembly drawing shown in Figure 5.
Once the ring is centered tighten all bolt to 40ft-lb following the pattern shown in Figure 5.
5. Add the second floating flange to the assembly. Thread one bolt to the valve body and hand tighten. Add the floating
flange sandwich plate while pushing the header assemblies apart. Add the rest of the bolts and hand tighten. Center the
flange in the same way as shown in step 4. Tighten all bolts.
6. Tighten the large header grooved clamps.
