Wafer Type Butterfly Valves: Introduction, Product Features & Technical Parameters

Wafer Type Butterfly Valves refer to a type of valve that adopts wafer connection type. During installation, flanges are welded on both sides of the pipeline, and the butterfly valve is clamped and connected through perforated bolts. The closing part (valve clack or butterfly disc) is a disc that rotates around the valve shaft to achieve opening and closing, making installation and use convenient.

Wafer Type Butterfly Valves are suitable for water supply and drainage, gas pipelines in industries such as medicine, chemical industry, petroleum, electric power, textile, and papermaking, serving to regulate flow and cut off media. The applicable temperature is ≤80℃.

Product Features of Wafer Type Butterfly Valves

• Simple and compact structure, small and lightweight, easy to disassemble, assemble and maintain, and can be installed in any position.

• 90-degree rotation for quick opening and closing.

• The flow characteristic tends to be linear, with excellent regulation performance.

• Selecting different materials for components can make it applicable to various media.
