6. Insert valve into guide and tap valve lightly into place
a few times.
7. Remove valve and check where the Prussian Blue™
indicates seat contact on the valve face. The valve
seat should contact the middle of the valve face or
slightly above, and must be the proper width.
* If the indicated seat contact is at the top edge of the
valve face and contacts the margin area (Item 2) it is
too high on the valve face. Use the 30° cutter to
lower the valve seat.
* If too low, use the 60° cutter to raise the seat. When
contact area is centered on the valve face, measure
seat width.
* If the seat is too wide or uneven, use both top and
bottom cutters to narrow the seat.
* If the seat is too narrow, widen using the 45° cutter
and re-check contact point on the valve face and
seat width after each cut.
NOTE: When using an interference angle, the
seat contact point on the valve will be very
narrow, and is a normal condition. Look for an
even and continuous contact point all the way
around the valve face (Item 3).
