sion (1) interferes with the stop (2), move the stop
slightly to remove interference. DO NOT rotate stem!
6. Aligning the slot in the handle with drive on the stem
extension (1), lower the handle straight down over the
threaded rod (5) and in line with the stem extension
drive until it is completely engaged. NOTE: When look-
ing down at the top of the valve, the cast lettering and
“OPEN” arrow on the handle should be visible. If they
are not visible the handle is installed upside down.
7. Install the washer (7) over the threaded rod onto the
handle. Thread handle nut (6) onto threaded rod and
tighten handle nut (6) to torque value listed in Table 5.
8. Confirm ball is in fully open position.
9. Rotate stop (2) until the stop contacts the side of the
stem extension stop boss (1) (see Figure 14).

10.
Tighten the stop screws (3) to the values listed in
Table 6.
11. Close, and then open the valve making sure the stem
extension is against the stop. Check the ball to confirm
full open position. If the ball is not in the full open
position with the stem extension against the stop,
loosen the stop screws (3) and make any necessary
adjustments by rotating the stop (2). Retighten the
stop screws (3) to the values listed in Table 5.

ACTUATOR MOUNTING
When these valves are equipped with an actuator, and the
actuator is removed to service the valve, proper alignment of
the actuator driver and valve stem is essential when the actu-
ator is remounted.
7 .1 General
These actuator mounting instructions describe the steps
required to assemble the
Jamesbury
3”, 4” & 6”(DN 80, 100 &
150) ASME Class 150; and the 3”, 4” & 6”(DN 80, 100 & 150)
ASME Class 300, Standard Bore, Non-trunnion Series 7000
Model C standard and
Emission-Pak
Flanged Ball Valves to
actuators. Linkage kits that are needed to mount specific Metso
actuators to different types and sizes of
Jamesbury
valves can
be identified by Metso or your authorized Metso Distributor.
WARNING:
FOR YOUR SAFETY IT IS IMPORTANT THAT THE FOLLOWING
PRECAUTIONS BE TAKEN!
BEFORE INSTALLING THE VALVE AND ACTUATOR, BE SURE THE
INDICATOR POINTER ON TOP OF THE ACTUATOR IS CORRECTLY
INDICATING THE VALVE’S POSITION. FAILURE TO ASSEMBLE THESE
TO INDICATE THE CORRECT VALVE POSITION COULD RESULT IN
DAMAGE OR PERSONAL INJURY!
WHEN ISTALLING A LINKAGE KIT OR SERVICING THE VALVE/
ACTUATOR ASSEMBLY, THE BEST PRACTICE IS TO REMOVE THE
ENTIRE ASSEMBLY FROM SERVICE!
AN ACTUATOR SHOULD BE REMOUNTED ON THE SAME VALVE
FROM WHICH IT WAS REMOVED. THE ACTUATOR MUST BE
ADJUSTED FOR THE PROPER “OPEN” AND “CLOSE” POSITIONS
EACH TIME IT IS REMOVED!
THE LINKAGE KITS HAVE BEEN DESINGNED TO SUPPORT THE
WEIGHT OF THE METSO ACTUATOR AND RECOMMENDED
ACCESSORIES. USE OF THE LINKAGE TO SUPPORT ADDITIONAL
EQUIPMENT OR ADDITIONAL WEIGHT SUCH AS PEOPLE, LADDERS,
ETC, MAY RESULT IN THE FAILURE OF THE LINKAGE, VALVE OR
ACTUATOR ; AND MAY CAUSE DAMAGE OR PERSONAL INJURY!

Valve Preparation
1. With the valve removed from the pipeline, turn the
valve to the closed position.
2. On valves with handles, remove the handle, handle
bracket, and any accessories that may be attached to
the bonnet surface. DO NOT loosen the bonnet stud
nuts (30), see (Figure 19 or 20).
7 .3
Bracket Preparation – (see Figure 15)
1. Roll the bearing strip (3) about its length into a circular
shape.
2. Place the bearing strip (3) into round opening in the
top center of the bracket (2). Ends of the bearing must
not overlap.
3. Slide the bearing (3) into the bracket (2) until about
half of its width is protruding from the bottom of the
top bracket flange.
4. Inspect the coupling (1) and locate the end that will
engage the actuator.
