Switch form

The solenoid valve is driven by the coil and can only be turned on or off, and the action time is short when switching.

The drive of electric valve is usually driven by motor, on or off action needs a certain amount of time simulation, and can be adjusted.

Nature of the work

The general flow coefficient of solenoid valve is very small, and the working pressure difference is very small. For example, the general 25 caliber solenoid valve flow coefficient is much smaller than the 15 caliber electric ball valve. The solenoid valve is driven by the solenoid coil, which is easy to be damaged by voltage shock. Equivalent to the role of the switch, that is, on and off two functions.

Electric valve is generally driven by motor, more resistant to voltage shock. Solenoid valve is quick to open and close, and is generally used in small flow and small pressure, requiring high switching frequency of the electric valve reverse. The opening of the electric valve can be controlled, the state is open, closed, half open and half closed, which can control the flow rate of the medium in the pipeline, and the solenoid valve can not meet this requirement.

Solenoid valve power outage can be reset, electric valve to such a function needs to add reset device.

Applicable process

Solenoid valves are suitable for some special process requirements, such as leakage and special fluid medium, which is expensive.

Electric valve is generally used for adjustment, and there are also switches, such as: fan coil end.
