Fastening actuator on the valve
Actuator should be secured directly to the valve using proper bolts or via a
proper interface.
After assembly, the actuator can operate in any position.
However:
•
do not handle the actuator by handwheel to avoid damage on actuator
gearing.
•
cable glands must not be oriented upwards (loss of water tightness).
•
It is recommended not to position motor downwards.
