If it is a metal sealed valve, it will certainly have a long service life than the elastic sealed valve, and it is basically impossible to achieve complete sealing. Originally, metal seal can adapt to high temperature, but elastic seal is limited in this respect. 　　　　

Finally, because the electric three-way ball valve is actually only an intermediate part and equipment, and other equipment will be connected at both ends, the model and size of the connection must be accurate. Select the corresponding model and size according to the interface size of the corresponding other machines. If the two pieces cannot be connected seamlessly, the electric three-way ball valve will lose its significance of existence.
