Gate valves are classified according to sealing form

Gate valves are classified according to sealing form:
Metal seal gate valve: The gate plate and valve seat are usually made of metal materials, such as stainless steel, which have good high temperature resistance and wear resistance;
Elastic sealing gate valve: The gate plate and valve seat are usually made of rubber, polytetrafluoroethylene and other elastic materials, which have good sealing performance and are suitable for some corrosive media.
Ordinary gate valve: generally used in general industrial pipeline systems, suitable for the control of conventional media;
High-pressure gate valve: suitable for high-pressure pipeline systems and has good pressure resistance;
High temperature gate valve: suitable for the control of high temperature media, with good high temperature resistance.
