2205 super duplex steel 4A material flange ball valve ASTM A240/A240M-01 A995 Gr.4A-CD3MN is an industrial valve specially designed for handling corrosive, high-temperature, and high-pressure fluids. This ball valve adopts A995 Gr.4A-CD3MN duplex stainless steel as the main construction material. This dual phase steel is a composite material that combines the characteristics of austenite and ferrite. It has excellent corrosion resistance and is particularly suitable for handling fluids containing chlorides, hydrogen sulfide, and other corrosive substances. This material performs well in high temperature and high pressure environments, making it highly suitable for harsh industrial conditions.

Ball valve design: A995 Gr.4A-CD3MN duplex steel ball valve uses a ball as the valve core, and controls the fluid passage by rotating the ball. This design allows for quick opening and closing operations, as well as precise flow control in the middle position. The sealing performance of ball valves is usually excellent, ensuring that the valve will not leak when closed. High temperature and high pressure applications: This dual phase steel ball valve is suitable for high temperature and high pressure conditions and is commonly used in oil and gas extraction, refining, chemical processing, and other similar applications. They can withstand the stress of high-temperature steam, high-pressure gas, and corrosive liquids, ensuring the safety and reliability of the system. Corrosive fluids: Due to the corrosion resistance of A995 Gr.4A-CD3MN duplex steel, these ball valves are highly suitable for handling acidic, alkaline, and other corrosive fluids. They are not easily affected by corrosion and oxidation, therefore they have a long lifespan in these environments. Reliability and Durability: This type of dual phase steel ball valve typically has excellent reliability and durability. Their design and material selection enable them to work for long periods of time in harsh environments, reducing the need for maintenance and replacement. In summary, A995 Gr.4A-CD3MN duplex steel ball valve is a very important type of industrial valve in high temperature, high pressure, and corrosive fluid environments. Their design and material selection enable them to provide reliable fluid control under extreme conditions, ensuring smooth operation of industrial processes. These valves play a critical role in petroleum, chemical, refining, natural gas, and other fields, providing critical support for various engineering projects.
