The ultimate solution for highly corrosive and high-cleanliness applications

In critical processes involving strong acids, strong alkalis, organic solvents, or high-purity media in industries such as chemical engineering, pharmaceuticals, metallurgy, and environmental protection, ordinary metal valves often face severe challenges such as rapid corrosion, media contamination, and frequent leaks. Detora’s BTV-TF Lined butterfly valves, with its unique "metal skeleton + fully enclosed anti-corrosion lining" structure, perfectly solve this problem, becoming the most reliable and economical isolation and control equipment for corrosive and high-cleanliness environments.

The design philosophy of the lined butterfly valve is "a balance of rigidity and flexibility." It combines the high strength of the metal valve body with the excellent corrosion resistance of engineering plastics/elastomers, achieving a protective effect greater than the sum of its parts (1+1>2).

Rugged metal frame: The valve body, stem, and disc are made of cast iron, cast steel, or stainless steel, providing robust mechanical support and pipeline connection strength, withstanding system pressure and pipeline stress.

Comprehensive corrosion protection lining: A dense, continuous lining layer completely covers the valve body cavity, the butterfly plate surface, and the parts of the valve stem that come into contact with the media. This barrier completely isolates corrosive media from all metal components, making the valve virtually impervious to corrosive substances.

Precise sealing design: Utilizing an integrally molded lip seal edge made of the lining material or in conjunction with a PTFE valve seat, a tight fit with the butterfly plate is achieved, ensuring zero leakage.
