The difference between electric valves and solenoid valves
The main differences between electric valves and solenoid valves lie in their driving methods, working natures, applicable processes, and structural complexities.
1. Driving method:
Solenoid valves are driven by coils and can only achieve the actions of opening or closing. The action time is short when switching, and it is generally used in occasions with small flow and small pressure, and where high switching frequency is required.
The drive of electric valves is generally by a motor, which can achieve the actions of opening or closing, but it takes a certain amount of time to complete, and it is suitable for regulation and pipelines with larger diameters.
2. Working nature:
The flow coefficient of solenoid valves is generally very small, and the working pressure difference is also very small, which is 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, which is suitable for occasions of regulation and those that require flow rate control.
3. Applicable process:
Solenoid valves are suitable for some special process requirements, such as leakage and special fluid media, and the price is relatively expensive.
Electric valves are generally used for regulation, and there are also applications of switching quantities, such as at the end of fan coil units.
4. Structural complexity:
The structure of solenoid valves is simple, but relatively precise, and generally only has two states of opening and closing, and the requirement for the cleanliness degree of the medium is relatively high.
The structure of electric valves is relatively more complex than that of solenoid valves, and the required circuits are also a little more complex.
To sum up, the choice of using electric valves or solenoid valves depends on specific application requirements, such as whether flow rate regulation is needed, the applicable working environment, and cost considerations and other factors.
