The Wafer Type Butterfly Valve valve mainly completes the operation of opening or closing the valve by rotating the disc-shaped butterfly plate in the valve body around the central axis, and the rotation angle is between 0-90°.
When the rotation angle is 0°, the disc is parallel to the valve body, at this time the valve is in a fully closed state and stops flow; when the rotation angle is between 0° and 90°, the disc and the valve body form a certain angle, At this time, the valve is in a semi-open and closed state, which can adjust the flow of the medium in the pipeline;
When the rotation angle reaches 90°, the disc is perpendicular to the valve body, the valve is in a fully open state, and the valve flow reaches the maximum value.
Valves with metal seals with long-life valves are generally higher than elastomeric seals, but are also difficult to seal completely. Metal seals can accommodate higher temperatures, elastic seals have defective temperature extremes.
If you need to use a flow control valve as the main thing is to choose the correct size and type of valve. It is especially suitable for the production of large diameter valves. Butterfly valves are not only widely used in petroleum, natural gas, chemical, water treatment and other industries in general, but also in cooling water systems of thermal power plants.
Butterfly valves are usually used for both clip and flanged butterfly valves. The valve connection between the two pipeline flanges of the bolt-clamped butterfly valve is a flanged valve with flange bolts on both ends of the pipeline flange valve.
