Fluorine-lined Butterfly Valve

Our Gate Valve with Flange has been a strong product since we Strong acids and bases will damage normal metal valves. Even stainless steel can fail. Our Fluorine Lined Butterfly Valve solves this problem. The inside of the cast iron or cast steel body and the disc are lined with a thick layer of F46 or PFA. This lining resists almost all chemicals. So you get a low-cost solution for strong corrosive conditions. We use a center-line structure. The stem and disc have a one-piece blow-out proof design. The most important part is the lining process. We use high-temperature compression molding. The lining sticks strongly to the body. There are no bubbles or cracks. The surface is smooth. It also has self-lubrication. So the opening and closing torque is light.

Some customers ask us about vacuum conditions. They worry the lining may fall off or get sucked in. Normal lined valves can have this problem. But Suhao improved the dovetail groove design and lining thickness. Our Fluorine Lined Butterfly Valve can handle some negative pressure. You can buy it with our fluorine lined ball valves and fluorine lined globe valves. This gives you a full set of corrosion-resistant solutions for your chemical plant. We have the TS special equipment license. We also follow the GB/T 22642 standard. Our lining workshop has good environmental protection equipment. This meets local rules. So we can keep producing steadily.
