Comparison between solenoid valve and electric valve

1. Nature of work:

The driving method of the electric valve is generally a motor, which is more resistant to voltage shock. The solenoid valve is fast open and fast closed. It is generally used in small flow and small pressure, and the electric switch is required in the place where the switching frequency is large. The opening degree of the electric valve can be controlled, the state is open, closed, half open and half closed, and the flow of the medium in the pipeline can be controlled and the solenoid valve cannot meet this requirement.

Solenoid valves generally have a small flow coefficient and a small difference in working pressure. For example, a general 25-caliber solenoid valve has a smaller flow coefficient than a 15-caliber electric ball valve. The solenoid valve is driven by an electromagnetic coil and is relatively easily damaged by voltage surges. Equivalent to the role of the switch, is the role of opening and closing.

Solenoid valves can be reset by general power failure. For such functions, electric valves require a reset device.

2, switch form:

The drive of the electric valve is generally driven by a motor. It takes a certain amount of time to simulate the opening or closing action, and can be adjusted.

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

3. Applicable technology:

Electric valves are generally used for adjustment and also have a switching quantity, such as: fan coil end.

Solenoid valves are suitable for some special process requirements, such as leakage, special fluid media, etc., which are more expensive.
