The Hastelloy-C Double Offset Butterfly Valve is engineered to provide superior performance in highly corrosive environments. With a double offset design, this valve reduces friction between the disc and seat, ensuring a longer service life and a tight shutoff. Equipped with a pneumatic actuator, it offers fast and efficient automated control, making it ideal for industries such as chemical processing, petrochemical, and marine applications where resistance to corrosive media is critical.

Double Offset Design for Extended Lifespan:
The valve's disc is slightly offset from the seat, minimizing wear and tear during operation and ensuring a bubble-tight seal.

Hastelloy-C Material for Corrosion Resistance:
Manufactured from Hastelloy-C, known for its exceptional resistance to a wide range of corrosive chemicals, acids, and salts.

Pneumatic Operation for Fast and Efficient Control:
The pneumatic actuator allows for quick response and precise control, enhancing system automation and safety.

High Temperature and Pressure Tolerance:
Suitable for high-temperature and high-pressure applications, providing reliable performance in extreme conditions.

Low Maintenance Design:
