1. Operation mode:
The manual stop valve needs to manually rotate the handle or push and pull the handle to open or close the valve, while the electric stop valve is driven by an electric motor and operates the valve by the rotation of the motor. Relatively speaking, the operation of the electric stop valve is more convenient and quicker.
2. Control mode:
The control of the manual stop valve is completed by the operator directly through manual operation, while the electric stop valve can be connected to the control system to achieve remote control and automatic control. The electric stop valve can be used in conjunction with other automation equipment to achieve centralized control and automatic control.
3. Reliability:
There is a certain risk of circuit failure in the transmission and execution of control signals for the electric stop valve, while the operation of the manual stop valve is directly controlled by manual control, and there is no risk of circuit failure. At the same time, in special circumstances such as power outages, the electric stop valve may not work properly, while the manual stop valve can continue to be used.
