Linking stem valves from Henan Shangfa Valve Co. Ltd offer unparalleled efficiency and reliability for various industrial applications. Designed with precision, our DN200-2200 valves boast a robust construction of cast steel, ensuring durability and longevity.

Featuring a three-bar cut-off butterfly design, our valves guarantee optimal performance with a four-linkage mechanism driven by a butterfly valve drive device. This mechanism facilitates smooth valve opening and closing, maintaining stringent seal integrity for extended periods.

Suitable for blast furnace hot blast systems and a range of gas and flue applications, our valves excel in compactness, lightweight design, and ease of installation.

Leveraging finite element analysis and patented technologies, our valves are engineered for high-temperature and high-pressure environments, ensuring reliable operation even under demanding conditions.

With special sealing compensation, wear-resistant coatings, and multi-layer sealing structures, our valves offer exceptional resistance to wear and corrosion, promising extended service life and minimal maintenance requirements.
