Ordinary Electric Actuator

Split structure (commonly referred to as an ordinary electric actuator):

The control unit is separated from the electric actuator, and the electric actuator cannot separately control the valve, and the control unit must be controlled. The external controller or control cabinet is generally used in conjunction with the control box.
The disadvantage of this structure is that it is inconvenient to install the entire system, increasing wiring and installation costs, which is prone to failure. When a fault is faulty, it is not convenient to diagnose and maintain, and cost-effective is not ideal.
