4. Insert the seat ring into the seat ring cavity with
the correct shutoff surface facing the V-notch ball
and shaft. The seat ring will cover the face seal
installed in step 3.
5. Place the second face seal (key 8) on the seat
ring (key 4).
6. Apply anti-seize lubricant to the gasket surface in
the valve body. Install the gasket (key 11), while
making certain that the concave surface of the
gasket is up (hump surface of gasket down).
7. Apply anti-seize lubricant to the threads and
bottom of the retainer (key 5) only in the area that
contacts the gasket. Thread the retainer into the
valve body.
8. Refer to figure 7. Find the correct retainer torque
for the valve size. With the appropriate tool, tighten
the retainer to the torque listed in figure 7.
9. A gap between the seat ring (key 4) and retainer
(key 5) allows the seat ring to self-center. Applying
the proper amount of torque during installation
should position the retainer and seat ring properly.
Use a feeler gage to measure between the parts as
