wafer eccentric butterfly valve

Item No.: D373H

Product Usage

The D373H and D373Y wafer-type hard-sealed butterfly valves are made of precision J-shaped elastic sealing ring and three-eccentric multi-layer metal hard sealing structure. They are widely used in metallurgy, electric power, petrochemical, and water supply and drainage with medium temperature ≤ 425 °C. On industrial pipelines such as municipal construction, it is used to regulate flow and load fluid.
