Nature of the work Solenoid valve

Nature of the work:
Solenoid valves generally have a small flow coefficient and a small working pressure difference. For example, generally the flow coefficient of a 25-caliber solenoid valve is 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 relatively resistant to voltage shocks. Solenoid valves are quick-opening and quick-closing, and 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. Electric valves need to add a reset device to have such a function.
