4.2. Actuator Mounting
Note:
Prior to mounting, the part-turn actuator must be checked for any damage
Damaged parts must be replaced by original spare parts
4.2.1. Mounting is most easily done with the valve shaft pointing vertically upward. But mounting is also
possible in any other position; the actuator may be mounted in any position.
4.2.2. The HQ-series electric actuators are supplied with a female drive output. The ISO5211 bolt patterns
are provided for actuator mounting. The actuator drive bush is removable for ease of machining. It
is mandatory for the actuator to be firmly secured to a sturdy mounting bracket or directly
mounted to the valves’ ISO mounting pad. High tensile bolts or studs with spring locking washers
must be used.
4.2.3. The valve output shaft must be in lined with the actuator output drive to avoid side-loading the
shaft. To avoid backlash, flexibility in the mounting bracket or mounting should not be allowed.
CAUTION:
Do not attempt to work on your HKC actuator without first shutting off the incoming power.
Do not attach ropes or hooks to the hand wheel for the purpose of lifting by hoist
