''Hurko'' HKJ series intelligent electrical angle travel actuators have two main types: HKJ On-Off part turn valve actuator and HKJM Modulating part turn valve actuator. This is a very important field control equipment, has been widely used in electricity station、metallurgy、petroleum、chemistry industry、water conservancy、machine、light industry、fire protection、environment protection department and all so. The actuator, combined with a valve that can be one of the ball vale、 butterfly vale、 Air-throttle vale and all so, is appropriate to the fields of pipeline flow control、pollutants dumping、water treatment、paper making、ship building etc. Even in badly dangerous environment it can work reliable for its terse design. “Hurko” HKJ series part turn valve actuator provides you the most reasonable scheme in the range of 60Nm~2500Nm.
FULL PROTECTION
1. Torque protection: a sensor serve as overload protection for the entire valve travel, and you can set different torque volume between 40~120% of rated torque.
2. Limit protection: set this function as availability, the actuator should stop automatically while the valve position reaches the limit position.
3. Automatic phase rotation correction: actuator monitors the phases and run in the correct direction regardless of the sequence of power supply connection that is realized through a phase rotation correction Boolean logical calculation. Without this function it may damage the valve in unconsciously.
4. Instantaneous reversal protection: the motor control logic automatically add a time-delay in switching the motor when the actuator is ordered to reverse direction instantaneously, this function can preventing unnecessary wear to the valve stems and gearboxes.
5. *Phase failure protection: actuator real tine monitors all three phases of the power supply during operation to prevent lose phase action. (3-phase power supply only)
6. Valve Jammed protection: electric latching inhibits the actuator torque protection function around 5 seconds and allows the motor to generate 2 times rated torque to unseat the stuck valves while starting operation signal is enabled, if the actuator in the above-mentioned second time have no movement, control circuit will cut off the power supply of the motor to prevent the further valve damage or motor burn out.
7. Motor thermal protection: two thermostats are embedded in the windings for provide thermal-protection by de-energised motor in the event of motor over the maximum temperature.
8. Electric protection: the input and output signal channel of circuits are designed as photoelectric isolate model.
