Switch mode:
1. Solenoid valve through the coil drive, can only be open or closed, switch time is short.
2. Electric valve driver is generally used motor, open or close action to complete the need for a certain amount of time simulation, you can do to adjust.
Working property:
1. Electromagnetic valve general circulation coefficient is very small, and the working pressure difference is very small. For example, the general 25 diameter solenoid valve flow coefficient than the 15 diameter of the electric ball valve is much smaller. Solenoid valve driven by the electromagnetic coil is relatively easy to be damaged by voltage impact. Equivalent to the role of the switch, which is open and close the 2 roles.
2. The electric valve is generally used motor, compared with the voltage impact. Solenoid valve is fast open and close, generally used in small flow and small pressure, the requirements of large switching frequency of the local electric valve on the contrary. Electric valve opening of the valve can be controlled, the state has opened, closed, half open and half closed, you can control the flow of media in the pipeline and the solenoid valve can not reach this requirement.
3. The solenoid valve can be reset, the electric valve to such a function needs to be reset device.
Applicable process:
1. The solenoid valve is suitable for some special process requirements, such as leakage, fluid medium special, the price is more expensive.
2. The electric valve is generally used to regulate, but also the amount of the switch, such as: the end of the fan coil.
Use situation:
1. Electromagnetic valve can be operated valve, pneumatic butterfly valve device for pneumatic, is installed in the pneumatic actuator side, so that you can power to control the gas actuator of switch to realize the remote control.
2. The electric valve is an electric device, installed in the valve products, to achieve power control.
