1. The electromagnetic valve uses the electromagnetic principle to guide the movement of the valve core using 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, and low price. Moreover, it can only control the opening and closing action of the valve, which is suitable for use in pipelines with small diameters.

Solenoid valves are normally installed in small diameter pipelines, and are suitable for use in small diameter pipelines that require rapid 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 can be affected by voltage changes, which is relatively easy to damage, and has a short working time. Solenoid valves are similar to gate valves, which have only two functions: opening and closing, and cannot regulate the flow of pipeline media.

Electric valves can be used in larger diameter pipelines, with a wide range of applications. Electric valves are applicable to two-way motors as the driving components of the valve. The rotation of the motor drives the valve to open and close. The degree of opening and closing can be adjusted, allowing the valve to complete a half open and half close operation, controlling the flow of media.

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 of pipeline media, and digital signal control can also be used in specific pipeline environments.

3. Applicable scope of electric valve and solenoid valve:

The solenoid valve has excellent leak resistance, rapid opening and closing, and low power. It is suitable for use as a cutoff in some corrosive, toxic, and other chemical pipelines. Electric valves are mostly used for regulating pipe flow, and are normally installed at the outlet of air supply and refrigeration pipelines. They can also be used in liquid pipelines. They are widely used in pipelines such as canned pipelines and sewage treatment pipelines in the production of alcoholic beverages.
