The Comparison between Solenoid Valve and Electric Valve
1. The nature of work:
The actuating method of electric valve is usually by using motors, which are more resistant to voltage shock. Solenoid valve quickly opens and closes, are usually used in occasions where the flow and pressure is small and a large switching frequency is required. The opening of the electric valve can be controlled. There are these types of state: open, closed, half open half closed. The flow of the medium in the pipeline of electric valve can be controlled while solenoid valve can’t meet this requirement.
Usually solenoid valve has very small flow coefficient and working pressure difference. Solenoid valve is actuated by electromagnetic coil, so it’s more likely to be damaged by voltage shocks.
Solenoid valve can be reset when the power is off while a reset device needs to be installed on electric valve to achieve such a function.
2. The switching form:
Electric valve is usually actuated by motors. It takes a certain amount of time for the opening or closing action to complete. Solenoid valve is actuated by electromagnetic coil, can only be opened or closed. The switching time is short.
Electric sanitary valve is generally used for regulation, such as fan coil end. Solenoid valve is suitable for some special processing requirements, such as leakage, fluid medium. It’s more expensive.
