High-performance wafer butterfly valve is an industrial valve for precise flow control.
1. High-performance wafer butterfly valves are usually made of materials such as stainless steel, carbon steel or other corrosion-resistant alloys to ensure corrosion resistance and high temperature resistance.
2. The valve seat of high-performance butterfly valve is the biggest difference from ordinary double eccentric butterfly valve.
3. Bidirectional sealing: High-performance butterfly valves provide bidirectional sealing, which can effectively seal in both flow directions.
4. High-performance butterfly valves are the unique type which can be used for throttling.
5. CF3 stainless steel is the cast equivalent of 304L stainless steel, known for its corrosion and oxidation resistance. It performs well in mildly corrosive environments such as weak acids, chlorides and fresh water.
6. The polished surface can be used in systems such as drinking water.
