The ceramic star valve can work at high temperatures, adapt to the high temperature environment during lithium battery production, and is not easily deformed or damaged. Moreover, the ceramic star valve has good sealing performance, ensuring that materials will not leak during transportation and guaranteeing a clean and safe production environment. Due to these characteristics of ceramic star valves, they are widely used in various industrial productions.
