Instruction Manual
D103164X012
For service applications involving scale formation that sets up and "freezes" mating parts, supplementary
recommendations for disassembly can be provided by your
Assembly
WARNING
Observe the steps in the WARNING at the beginning of the Maintenance section.
Reference figures 9 and 10.
CAUTION
Trim parts are made from brittle material, handle with care to avoid chipping or breakage.
1. Clean all surfaces of the parts to be used. Ensure all mating surfaces are in good condition and free from scratches
and dents. Replace worn parts. Fit new gaskets (key 13 and 21) and packing (key 15).
2. Position the valve body with flow arrow uppermost.
3. Fit the valve body liner (key 2) into the valve body, aligning cross‐holes with shaft bore axis.
4. Fit the bearings (key 7) through the valve body liner into the valve body.
5. Place bearing shrouds (key 6) over the bearings and through the valve body liner to contact faces in the valve body
bore.
6. Orientate the ball (key 3) so that the lug with the location slot will be on the non‐drive side of the valve body, that is
opposite from the actuator. Place the ball on a wad of rag to rest in the bottom of the valve body with the lugs
uppermost. Fit the drive shaft (key 8) through the bearing on the drive side and into the hexagon hole of the ball,
aligning the holes for the shaft pins. With a splined shaft, the indicator line on the splined shaft end should be on the
ball side to indicate the ball "seat location." Fit the follower shaft (key 9).
7. Fit the shaft pins (key 10) through the ball and into the shaft using a pin punch (figure 7). Position the pins
approximately centrally about the shaft axis.
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. Fit the spring (key 19), gasket (key 21), and plug (key 20).
