Ceramic lined star valves have unique advantages in corrosion resistance. Due to the high hardness and chemical stability of ceramic lining, many chemic
als cannot corrode its surface. Therefore, it is widely used as lining material for storage tanks, reactors, pipelines and other equipment in various chemical factories and laboratories. The use of ceramic lining can reduce equipment corrosion, extend the service life of equipment, and improve production efficiency.
*Good sealing: Ensure that materials will not leak during transportation, ensuring a clean and safe production environment.
*Easy to clean: The ceramic surface is smooth and not easily adhered to materials, making it easy to clean and maintain.
*Precise control: capable of achieving precise control over the discharge volume to meet production process requirements.
