The ceramic star valve is easy to clean, with a smooth ceramic surface that is not easily adhered to materials, making it convenient for cleaning and maintenance. Moreover, it can achieve precise control over the discharge volume and meet the production process requirements. Due to these characteristics of ceramic star valves, they are widely used in various industrial productions.
