Features

1.  Superior Corrosion Resistance
    Nickel-aluminum bronze offers exceptional resistance to seawater, brackish water, and a wide range of chemicals, making it ideal for highly corrosive environments.

2.  Bidirectional Zero Leakage
    The geometry of the triple-offset design, combined with a metal-to-metal seal, ensures a tight, bubble-tight shut-off in both flow directions, providing reliable isolation.

3.  Excellent Erosion and Cavitation Resistance
    The C95800 alloy is known for its high strength and resistance to wear, making the valve highly durable in applications with high flow velocities or cavitation potential.

4.  Fire-Safe Design
    As a metal-seated valve, it is intrinsically fire-safe. In the event of a fire, the metal components will not burn or melt, maintaining a seal and preventing the escalation of the incident.

5.  Friction-Free Operation
    The triple-eccentric design ensures that the disc only contacts the seat at the point of full closure, eliminating friction and wear during operation. This drastically reduces operating torque and extends service life.

6.  High-Temperature Capability
    Unlike elastomer-seated valves, the all-metal construction allows it to handle much higher temperatures, suitable for hot fluids, steam, or heat-traced lines.
7.  Long Service Life and Low Maintenance
    The combination of a corrosion-resistant body, a wear-resistant sealing mechanism, and a friction-free operation results in an extremely long service life with minimal maintenance requirements.
8.  High-Pressure Rating
    The robust design and metal seat allow these valves to be used in higher pressure applications where soft-seated butterfly valves or other valve types would not be suitable.
9.  Stable and Reliable Seating
    The conical sealing geometry of the seat and disc creates a wedging effect as the valve closes, guaranteeing a consistent and reliable seal over countless cycles without galling.
10. Anti-Galling Properties
    Nickel-aluminum bronze has inherent anti-galling characteristics, which is critical for the metal-to-metal contact in the seat and disc, ensuring smooth operation and preventing seizure.
