The valve seal seat, also known as the sealing ring, is in direct contact with the medium inside the pipeline and serves to prevent the flow of that medium. When using valves, various media are present in the pipelines, such as liquids, gases, oils, and corrosive substances. Different valve seals are used in different locations to accommodate these various media. Well, valve seal materials can be mainly divided into two categories: metallic materials and non-metallic materials. Non-metallic seals are generally used in pipelines under normal temperature and pressure conditions, while metallic seals have a wider range of applications and can be used in high-temperature and high-pressure environments! Next, a brief introduction will be given to the operating conditions of various sealing materials, as well as the common types of valves.
