The Difference between Electric Valves and Electromagnetic Valves
The main differences between electric valves and electromagnetic valves lie in their driving methods, working natures, applicable processes, and structural complexities.
1. Driving methods:
Electromagnetic valves are driven by coils and can only achieve the actions of opening or closing. The action time is short during switching and is generally used in situations with small flow rates and small pressures where a high switching frequency is required.
The driving of electric valves is usually by a motor, which can achieve the actions of opening or closing, but it takes a certain amount of time to complete. It is suitable for regulation and larger-diameter pipelines.
2. Working natures:
The flow coefficient of electromagnetic valves is generally very small, and the working pressure difference is also very small. They are suitable for special process requirements, such as leakage and special fluid media.
Electric valves can control the flow rate of the medium in the pipeline and have multiple states such as opening, closing, and half-opening and half-closing. They are suitable for regulation and occasions where flow rate control is required.
3. Applicable processes:
Electromagnetic valves are suitable for some special process requirements, such as leakage and special fluid media, and the price is relatively high.
Electric valves are generally used for regulation and also have applications of on-off quantities, such as at the end of fan coil units.
4. Structural complexities:
The structure of solenoid valves is simple but relatively precise. Generally, there are only two states, opening and closing, and the requirement for the cleanliness of the medium is relatively high.
The structure of electric valves is relatively more complex compared to solenoid valves, and the required circuits are also more complex.
In conclusion, the choice of using electric valves or electromagnetic valves depends on specific application requirements, such as whether flow rate regulation is needed, the applicable working environment, and cost considerations.
