Hastelloy B series valves corrosion resistance feature: It has the good corrosion resistance performance in the reducible sour medium and so on the hydrochloric acid, sulfuric acid, phosphoric acid.

Hastelloy Butterfly Valves Corrosion Resistance Feature
It has a fine corrosion resistance performance in includes chloridion etc. oxidized acid, in includes in the oxidant reducible acid, in the nitration mixture and so on with reducible acid and oxidized acid. Its prominent characteristic has the fine corrosion resistance in the strong corrosion oxidability and the reducible sour medium.

Hastelloy Butterfly Valves Applications
Hastelloy butterfly valves find applications across industries where corrosion resistance and high-temperature capabilities are vital. They are commonly used in chemical processing, oil and gas, power generation, pharmaceuticals, water treatment, aerospace, marine, mining, and biotechnology sectors.
