‌Enamel-lined ball valve‌ is a valve with excellent corrosion resistance and good sealing performance, widely used in industries such as chemicals, petrochemicals, metallurgy, dyeing, and food processing. Its design features include:

Corrosion Resistance: The body and critical parts of the enamel ball valve are coated with a dense enamel layer, capable of withstanding the erosion of various acidic, alkaline, salt solutions, and organic solvents, particularly suitable for use in corrosive media.

‌Sealing Performance: Valves are equipped with abrasion-resistant and corrosion-resistant seals to ensure sealing effectiveness when closed. Sealing pairs are often designed with special features, such as line seals, to enhance sealing reliability.‌

Structure Design: The valve disc is designed with an upward lifting mechanism, where the disc moves upwards during operation, aiding in reducing material residue and clogging, and facilitating maintenance and cleaning. Additionally, the valve body features a V-shaped design, offering both lifting and lowering operating modes for the valve disc.

‌Operation Method: The enamel discharge valve can be selected with an appropriate operation method based on actual working conditions, such as manual or pneumatic. Pneumatic control allows for remote operation, enhancing production efficiency and safety.‌

‌Application Range: Widely used in coal chemical, petrochemical, rubber, papermaking, and other pipeline systems as a medium分流/合流 or flow direction switching device.‌

Maintenance and care

Regular maintenance is a crucial measure to ensure the long-term stable operation of the enamel discharge valve. Maintenance includes:

‌Inspect sealing devices: Ensure even pressure on the sealing rings and PTFE sealing rings to prevent leakage._

‌Lubricate screw‌: Maintain lubrication to prevent rust.

Avoid hard object impact: Avoid striking or scraping the porcelain surface while using tools.

‌Inspect Medium: Ensure the medium flowing through does not contain hard particles to prevent abrasion or clogging of the porcelain surface._‌
