VVT solenoid valve can control the connection line and break.
1. The structure of ordinary electromagnetic valve is generally composed of valve body, coil and electromagnetic core. There are generally wire connected electromagnetic valve and flange electromagnetic valve, which are normally closed and normally open.
2. The principle of solenoid valve is very simple, that is, the valve core is equipped with an electromagnet. When the electromagnet coil has electricity, the valve core is sucked up and the valve is opened
