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.
5.2
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. DO NOT
loosen the hex head cap screws (29), (see Figure 8).
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 INSTALLING 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 DESIGNED 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!
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
actuator is remounted.
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.

Bracket Preparation – (see Figure A)
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.

5. Insert the actuator end of the coupling (1) from the
bottom of the bracket (2) into the protruding bearing (3).
6. Press the coupling (1) upward until the bearing (3) sits
flush on the bearing shoulder of the coupling (1) and is
flush with the top flange of the bracket (2). (See Figure B)

Bracket Attachment to Valve
1. Lower the bracket/coupling assembly on the valve,
aligning the slot in the bottom of the coupling (1) with
top of the valve stem.
2. Align the four bracket mounting screw holes with the
tapped holes on the valve bonnet.
