What are the differences and differences between electric and solenoid valves?

The electromagnetic valve uses the electromagnetic principle to guide the movement of the valve core by the electromagnetic attraction force generated by the energized electromagnetic coil. The control mode is DO digital signal control, the solenoid valve has a single structure, the principle is simple, the price is low, and the valve can only be controlled by the switching action. Suitable for use in pipes with small calibers.

The driving device of the electric valve is a reversible electric motor. The valve control valve is driven by the motor for a certain period of time. The AI analog signal control can be used to adjust the flow of the pipeline medium, and the number can also be changed in a specific pipeline environment. Signal control.

Solenoid valves are normally installed in small-diameter pipes and are suitable for use in small-diameter pipes that require fast, frequent opening and closing of valves. The designed flow is small and the pressure of the valve is also low. The solenoid valve uses the suction force of the electromagnetic coil to drive the valve to open and close, which is simple and effective. At the same time, the solenoid valve coil is affected by the voltage change, which is relatively easy to damage and has a short working time. Solenoid valves are similar to gate valves. They only have two functions of opening and closing the valve, and the flow of the pipe medium cannot be adjusted.

Electric valves can be used in larger diameter pipes, and larger ones are applicable. The electric valve is suitable for the two-way motor as the driving component of the valve. The valve is opened and closed by the rotation of the motor. The degree of opening and closing can be adjusted, and the valve can be half-opened and semi-closed to control the flow of the medium.

The difference between the applicable range of electric valve and solenoid valve:

Solenoid valve has excellent anti-leakage performance, quick opening and closing, low power, suitable for use as a cut-off in some chemical pipelines such as corrosion and toxicity.

Most of the electric valves are used for the adjustment of the pipeline flow. They are normally installed at the air outlet of the air supply and cooling ducts, and can also be used in liquid pipelines. They are widely used in pipelines such as canned pipes and sewage treatment pipes for the production of beverages.
