Product Advantage

High-performance wafer butterfly valve is an industrial valve for precise flow control.

1. Wafer-type valve body construction minimizes space requirements and installation time.
2. 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.
3. The valve seat of high-performance butterfly valve is the biggest difference from ordinary double eccentric butterfly valve.
4. Bidirectional sealing: High-performance butterfly valves provide bidirectional sealing, which can effectively seal in both flow directions.
