The difference between solenoid valve and electric valve

1. Switching form:
The solenoid valve is driven by a coil and can only be opened or closed. The action time is short when switching.
Electric valves are generally driven by motors. It takes a certain amount of time to complete the opening or closing action, which can be adjusted.

2. Working nature:
Solenoid valves generally have a small flow coefficient and a small working pressure difference. For example, the flow coefficient of a 25-caliber solenoid valve is generally much smaller than that of a 15-caliber electric ball valve. The solenoid valve is driven by an electromagnetic coil, which is relatively easy to be damaged by voltage shock. It is equivalent to the function of a switch, which has two functions: on and off.
Electric valves are generally driven by motors, which are more resistant to voltage shocks. Solenoid valves are quick-opening and quick-closing. They are generally used in places with small flow rates and small pressures that require high switching frequency. The opposite is true for electric valves. The opening of the electric valve can be controlled, and the states are open, closed, half-open and half-closed. It can control the flow of the medium in the pipeline but the solenoid valve cannot meet this requirement.
Solenoid valves can generally be reset when the power is turned off. To achieve this function, electric valves need to add a reset device.

3. Applicable process:
Solenoid valves are suitable for some special process requirements, such as leakage, special fluid media, etc., and are more expensive.
Electric valves are generally used for adjustment, and they also have switching values, such as at the end of a fan coil unit.
