D343H-16C Triple Eccentric Metal Hard Seal Butterfly Valve

Model: D343H-16C

Pressure Rating: PN16 (1.6MPa) / Class 150 Compatible

Operation: Worm Gear Actuated

BodyMaterial: WCB Cast Steel

Engineered to meet the rigorous demands of North American industrial applications, our D343H-16C triple eccentric hard seal butterfly valve delivers reliable zero-leakage performance across water, air, natural gas, oil, and weakly corrosive fluids. Designed for compatibility with standard North American piping systems, it is widely used in food processing, environmental protection, petrochemical, power generation, and industrial automation projects in the USA and Canada.

  ✅ Key Performance Features (SEO & Conversion Focused)

• Triple Eccentric Hard Seal DesignThe offset disc structure eliminates friction between the butterfly plate and metal seat during operation, achieving bubble-tight shut-off with zero leakage. The near-zero wear sealing surface extends service life significantly, even with repeated use.

• Compact & Lightweight, Easy OperationThe streamlined structure saves installation space, while the worm gear drive mechanism reduces operating torque for smooth, effortless opening and closing. The linear flow characteristic ensures precise regulation for industrial control systems.

• High Durability & Versatile CompatibilityConstructed from robust WCB cast steel, this butterfly valve withstands pressures up to 1.6MPa (Class 150 equivalent) and a wide range of temperatures. It is compatible with various media including water, steam, oil, gas, and corrosive fluids, making it suitable for diverse industrial pipelines.

• Full Size Range for All ProjectsAvailable in sizes DN50 to DN1200, with standard flange dimensions (DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350, DN400, DN450, DN500, DN600, DN700, DN800, DN900, DN1000, DN1200) to meet the requirements of small-scale facilities and large industrial projects alike.
