Strong Corrosion Resistance:
- Nickel and nickel-based alloys exhibit excellent corrosion resistance. Their surfaces can form a stable “passive oxide film,” which effectively resists various corrosive media such as high-temperature concentrated alkali, sulfuric acid, hydrochloric acid, and phosphoric acid. This film prevents the valves from corrosion and damage, thus prolonging their service life.
Excellent Sealing Performance:
- Manufacturers adopt designs like the triple-eccentric sealing structure. This design ensures minimal wear between the valve seat and butterfly plate while providing an automatic sealing function that tightens further when closed. The sealing surfaces offer compensation, achieving zero leakage.
Reasonable Structural Design:
- Engineers design large-size butterfly plates with a truss structure, enhancing strength while creating a large flow-through area and low flow resistance. Additionally, these valves feature bidirectional sealing, allowing installation in any direction regardless of the medium flow or spatial position. Users can also mount the driving device in multiple positions for convenience.
Easy and Light Operation:
- Nickel butterfly valves are compact and lightweight. With components like worm-gear reducers, they become even easier to operate, simplifying installation and maintenance processes.
