The QT series electric actuators have small size, light weight, and high protection level, and can be widely used in industries such as petroleum, chemical, power generation, water treatment, and papermaking.
Suitable for butterfly valves, ball valves, air door baffles, and other valves that can rotate 90 degrees, it can meet various requirements of industrial automation control pipelines. It is a separate closed, adjustable, and intelligent remote control type, with automatic phase sequence correction and phase failure alarm protection functions for three-phase power supply. Equipped with motor overheat protection function. The input and output signal channels are optically isolated (capable of withstanding 2000V surge voltage) and have been replaced by traditional control methods using microelectronics technology, infrared remote control technology, and magnetic switch technology. There are various options for power supply, such as single-phase, three-phase three wire system, three-phase four wire system, etc.
