Product Introduction:
The valve body and butterfly plate are fully lined with PTFE (or PFA, FEP, UHMWPE), offering excellent corrosion resistance. It can be widely used in petroleum, chemical, electronics, metallurgy, medicine, electricity, environmental protection, and other industrial sectors. It can be used for controlling or on-off applications in pipelines carrying strong corrosive media such as acids and alkalis.
