IMPORTANT
Use gaskets whose inner diameter is greater than those of ULTRA YEWFLO and the
joint pipe. Exercise extreme care to prevent the gaskets from protruding into the flow
path.
The procedure for mounting a wafer type of ULTRA YEWFLO is the same no matter which type of
flange you use.
Horizontal Mounting
<1> Thread two collars each through each of the lower two bolts as shown in fig 4.2-
3.
<2> Evenly fasten the nuts and bolts, tightening both edges of ULTRA YEWFLO’s
brim onto each pair of collars.
<3> Make sure the process fluid is not leaking.
