Worm Gear Manual Operation Bi-Directional Tight Shutoff Triple Offset Butterfly Valve

Adopts triple eccentric offset structural design, the sealing surface separates completely during opening and closing with zero friction contact, avoiding sealing ring abrasion.

Equipped with CF8 stainless steel valve body and metal hard sealing pair, excellent high temperature resistance, suitable for high-temperature steam and hot flue gas pipelines.

Worm gear manual driving mechanism greatly reduces operating torque, the valve can be opened and closed easily with small manpower operation.

Metal hard seal bidirectional sealing design achieves reliable bubble-tight shutoff, effectively improving long-term pipeline sealing stability.

CF8 cast stainless steel material delivers outstanding anti-corrosion performance, resisting weak acid, alkali and high-temperature medium oxidation corrosion.

Frictionless switch eliminates the main wear factor of conventional butterfly valves, greatly extending the whole valve service cycle and lowering maintenance frequency.

Standard flanged end matches common industrial pipeline installation standards, convenient for on-site assembly, disassembly and overhaul.

PN16 nominal pressure rating meets the operation requirement of conventional medium-pressure industrial heating and chemical pipelines.

Overall casting structure has high structural rigidity, no deformation under long-term high temperature and pressure working conditions.

Manufactured and tested strictly in accordance with API 6D and API 609 standards, all finished valves pass API 598 inspection, with complete formal certification documents available for project accept
