HKC Electric actuators are suitable for intermittent control in automatic control loops that the system rate
of change is not more than 600 starts per hour . For the long travel, it should providing the average
torque required by the valve in mid stroke does not exceed 33% of the rated torque of the selected
actuator. The HKC actuator continual operation time is 15 minutes and motion proportion is 33.3%.
The HKC series actuator has the same function as the HKM series actuator. The operation menu is
also the same as the HKM series actuator. The HKC series actuator derives from the HKM series
actuator, but the HKM series actuator's start frequency is 1200 starts per hour under the modulating
torque. When you need high start frequency, you must select the HKM series actuator not the HKC
series actuator.
