CAUTION ON ASSEMBLY WITH A VALVE
7. ASSEMBLY WITH A VALVE
7-1 Names of parts
The actuator is removable from a valve, so that it is very easy to replace either part in case of trouble.
7-2 Assembly procedure
A : For a valve that does not have a mechanical stop on close side
A-1. Manually turn the valve and check if it is normal, and position it at full close.
(In case of a ball valve, position it at a full open.)
A-2. Bolt a bracket on the valve.
A-3. Tentatively bolt the actuator on the bracket.
A-4. Position the actuator at 0 % (close), then joint the output shaft and the valve stem with a coupling.
A-5. Secure the bolts.
A-6. Manually check that the actuator turns smoothly without eccentricity.
The assembly is over. For disassembly, work to the contrary.
B : For a valve that has a mechanical stop on close side
B-1. Check that the valve movement is normal, then position it at full close.
Be sure that the position is just inside the valve stop.
