Solenoid valve and electric valve difference

1. Switch form: solenoid valve driven by the coil, only open or close, the switch action time is short. Electric valve drive motor is usually used to open or close the action to complete the need for a certain amount of time analog, you can do to adjust. 2 nature of work: solenoid valve general circulation coefficient is small, and the working pressure difference is small. For example, the general 25-caliber solenoid valve flow coefficient than the 15-caliber electric valve is much smaller. Solenoid valve drive is through the electromagnetic coil, relatively easily damaged by voltage shock. Equivalent to the role of the switch is to open and close 2 roles. Electric valve drive motor is generally more resistant to voltage shocks. Solenoid valve is open and fast off, generally used in small flow and small pressure, requiring a large switching frequency electric valve instead. The opening of the electric valve can be controlled, the state of the open, closed, semi-open semi-off, you can control the flow of medium in the pipeline and the solenoid valve can not meet this requirement. Solenoid valve power can be reset, electric valve to such a function need to add reset device. 3. Applicable Process: Solenoid valve suitable for some special requirements, such as leakage, special fluid medium, the price is more expensive. Electric valve is generally used for regulation, but also the amount of switching, such as: fan coil end.
