8. Next install the packing. Fit the studs (key 17 ), packing box ring (key 14), packing set (key 15), packing follower

(key 16), and nuts (key 18). Adjust the packing tightness for use.

9. Before fitting the flow ring, tap the end of the bearing on the drive end to ensure that the ball/shroud assembly is

hard against the valve body inner recess location on the drive end.

10. Next fit the flow ring.

a. For one piece High Chrome Iron flow ring (key 4), fit into the valve body and valve body liner. Fit the gasket, (key

13) and flow ring retainer (key 5). Secure with retainer screws (key 22) and clips (key 23). Check that the ball

rotates freely.

b. For flow ring with ceramic insert, position the valve body on the valve body liner flange face with the ball secured

and facing upwards. Make sure the flow ring insert type (key 28) and flow ring insert (key 29) are clean and free of

grease and oil. Apply a bead of Loctitet 620 around the smaller outside diameter of the ceramic insert and push

the insert into the flow ring. Place shims on the upper ball face (recommended thickness 0.015 inch) and lower

the flow ring assembly into place. Secure with retainer, screws and clips. Push the insert down onto the shims

and allow the adhesive to set.

11. Coat thread of non-drive end body plug with Loctite 567 and fit gasket (key 21), spring (key 19), and plug (key 20)

to body. Tighten plug by hand until gasket contact is achieved. Continue to tighten body plug an additional

1/4-turn from gasket contact.
