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
.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).
For service applications involving scale formation
that sets up and "freezes" mating parts,
supplementary recommendations for assembly can
be provided by your Emerson Process Management
sales office.
Actuator Mounting
Use the appropriate actuator instruction manual, this
section of this manual, and figure 8 of this manual
when mounting the actuator or changing actuator
styles and positions.
1. To help ensure correct centering of the V-notch
ball (key 3) on the flow ring (key 4 or 28/29), be sure
the ball is closed when mounting the actuator (for
applications other than Spring Return Fail-Open).

2. Clean the valve shaft and actuator lever splines
to be sure the actuator lever will slide on easily. Only
drive the lever in if absolutely necessary.
3. Carefully wedge the ball solidly against the
actuator-side bearing to center the ball.
4. Keep the wedge in place while installing the
lever, if necessary. Remove the wedge after you
have clamped the actuator lever on the valve shaft
and have connected the lever to the actuator piston
rod or diaphragm rod.
Determining Mounting Position for
Spline Shaft/Lever Type
The actuator can be either right or left-hand
mounted, with the actuator on the right or left side
when viewed from upstream (see figure 8).
For right-hand mounting (standard), the ball will
be in the top of the valve body when the valve is
open and the shaft is horizontal. In this position the
ball rotates CW to Close.
For left-hand mounting, the ball will be in the top of
the valve body when the valve is open and the shaft
is horizontal. In this position the ball rotates CCW to
Close.
