Pre-installation
Verify the actuator’s nameplate to ensure correct model number, torque output, operating speed, voltage and
enclosure type before installation or use.
It is important to verify that the torque output of the actuator is appropriate for the torque requirements of the
valve and that the duty cycle of the actuator is appropriate for the intended application.

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
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.
The HQ-006 series actuators are supplied with Union joints & nuts; the Union joints are removable for the
ease of machining.
CAUTION
:
Do not attempt to work on your HKC actuator without first shutting off the incoming
power.
