1. The electromagnetic valve utilizes the electromagnetic principle to guide the movement of the valve core through the electromagnetic attraction generated by the energized electromagnetic coil. The control mode is DO digital signal control. The electromagnetic valve has a single structure, simple principle, low price, and can only control the opening and closing of the valve, making it suitable for use in pipelines with smaller diameters.

Electromagnetic valves are normally installed in small diameter pipelines and are suitable for use in small diameter pipelines that require quick and frequent valve opening and closing. The designed flow rate is small, and the pressure of the valve is also at a lower level. The electromagnetic valve uses the suction of the electromagnetic coil to drive the valve to open and close, which is simple and effective. At the same time, the electromagnetic valve coil is easily damaged due to voltage changes, and the working time is short. Electromagnetic valves, similar to gate valves, only have two functions for opening and closing the valve, and cannot regulate the flow of pipeline medium.

2. Electric valves can be used in larger diameter pipelines and have a wide range of applications. Electric valves are suitable for using a bidirectional motor as the driving component of the valve, which drives the valve to open and close through the rotation of the motor. The degree of opening and closing can be adjusted, allowing the valve to complete half opening and half closing operations, controlling the flow rate of the medium.

The driving device of the electric valve is a reversible electric motor, which drives the valve core to control the valve through a certain period of rotation of the motor. AI analog signal control is used to adjust the flow rate of the pipeline medium, and digital signal control can also be used in specific pipeline environments.

3. Applicable scope of electric and solenoid valves:

The electromagnetic valve has excellent leak resistance, fast opening and closing, low power, and is suitable for use as a cut-off valve in pipelines with corrosive, toxic, and other chemical substances. Electric valves are mostly used for regulating pipeline flow and are normally installed at the outlet of air supply and refrigeration pipelines. They can also be used in liquid pipelines, and are widely used in pipelines such as canned drinks and sewage treatment pipelines.
