5. MOUNTING ON VALVE
[Fig.5]
There are 2 mounting methods as shown in the illustrations.
Actuator is dismountable in case of trouble.
Support interface mounting
a) Confirm that power is off before making manual drive.
b) Confirm manually that the valve is normal, and then set it at full close.
c) Bolt the yoke on the valve.
d) Set an actuator at full close, and tentatively bolt it on the yoke.
e) Fix valve stem and actuator output shaft with coupling.
f) Secure bolts and fix the yoke and actuator.
g) Confirm manually that the valve turns smoothly without eccentricity.
Direct interface mounting
a) Confirm that power is off, and then set both valve and actuator at full close.
b) Fit the concavity of the mounting flange to actuator, and bolt them up.
c) Insert and fix actuator output shaft (female) to valve stem.
d) confirm manually that the valve turns smoothly without eccentricity.
