Split structure (usually called ordinary electric actuator):
The control unit is separated from the electric actuator. The electric actuator cannot control the valve alone, and the control unit must be added to realize the control. Generally, an external controller or control cabinet is used in conjunction with the control box.
The disadvantage of this structure is that it is inconvenient to install the entire system, increases wiring and installation costs, and is prone to failure. When a fault occurs, it is inconvenient to diagnose and maintain, and the price/performance ratio is not ideal.
