What are the control methods of electric actuators:
The key use of electric actuators in conjunction with gate valve equipment is to control the effect, which is a common electric valve in various industrial systems. The general control methods of electric actuators are generally divided into switch type (open-loop control) and adjustment type (closed-loop control). What are the operating methods of switching and adjusting electric actuators, and how to control them? Let's talk about the control methods of switching and adjusting electric actuators with valve electric actuators.
Switching electric actuator (open-loop control):
The switch electric actuator generally completes the opening and closing operation of the gate valve, and the gate valve is not in the switch position or fully closed position, so there is no need to accurately control the logistics. It is worth mentioning that due to different structural methods, switch electric actuators can also be divided into separate structures and integrated structures. When choosing a type, it is necessary to explain this point, otherwise there will always be conflicts with the control system during on-site assembly.
Electric actuator (closed-loop control):
Adjusting electric actuators not only has the function of integrated switch structure, but also accurately operates valves, thereby accurately regulating logistics.
