[0002] The valve is a pipeline accessory used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. The sealing ring is an important component on the valve, which increases the sealing performance of the interface. The selection of the sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring.
