Wafer Butterfly Valve Introduction The Wafer butterfly valve operates via a disc-shaped butterfly plate installed along the pipeline's diameter direction. The plate rotates within the cylindrical channel of the valve body around its axis, with a rotation range from 0° to 90°. At 90°, the valve is fully open. This valve features a simple structure, compact size, and light weight. It requires only a 90° rotation for quick opening and closing, thus providing excellent fluid control characteristics. When fully open, the thickness of the butterfly plate is the sole resistance to the medium's flow, resulting in minimal pressure drop. Butterfly valves offer two types of sealing: elastic and metal. The elastic seal can be positioned in the valve body or attached around the butterfly plate, accommodating different sealing efficiency and durability requirements. Features of wafer butterfly valve: Small and lightweight, easy to disassemble and maintain, and can be installed in any position. Using pipe flange clamping installation. simple and compact structure, 90 ° rotary opening quickly. Can add electric or pneumatic, known as imported electric rubber lined butterfly valve and imported pneumatic butterfly valve, remote control. Small operating torque, labor-saving lightweight. flow characteristics tend to straight line, good regulation performance. Can be used for regulation. the number of opening and closing tests up to tens of thousands of times, long life.
