Basic types of clamp type fluorine lined butterfly valves

  clamp-on Fluorine-lined Butterfly Valve It is a butterfly plate that rotates together with the valve stem as an opening and closing component, used to achieve the opening, closing, and adjustment of the valve. Clamp type fluorine lined butterfly valve There are many types, and there are two basic types, namely D71F4 and D71F46 (midline) fully lined clamp butterfly valves. They use a combination of two valve bodies, with the valve seat and inner lining integrated. When the valve is in operation, only the fully plastic valve seat and the lined butterfly plate come into contact with the medium. The product can withstand any medium corrosion except for molten alkali metals and elemental fluorine. The D71F46 valve stem and butterfly plate are integrated, and the surface is uniformly coated with a layer of FEP. The inner surface of the valve body channel is smooth, the fluid resistance is small, the CV value is high, the flow capacity is strong, and the torque is moderate. The four stage sealing structure is adopted, and the temperature resistant and anti-aging SI rubber elastic gasket valve seat is equipped outside the sealing surface to achieve zero leakage of the medium. The D41F4 and D41F46 flange connected butterfly valves, which are expanded from the above models, have fully lined valve bodies and semi lined stainless steel butterfly plates.
