ASTM A890 4A Ball Control Valve

The ASTM A890 4A Ball Control Valve is made from duplex stainless steel, specifically ASTM A890 CD3Mn, which is equivalent to the wrought super duplex stainless steel UNS S32205. This grade, also designated as ASTM A995 and ASME SA351/995, offers superior corrosion resistance and high strength, making it ideal for harsh environments. Known as J92205 or X2CrNiMoN22, the alloy features a balanced composition of austenitic and ferritic phases, providing excellent durability and resistance to extreme conditions. The valve includes a precision ball mechanism for smooth, accurate flow control and is suitable for high-pressure and high-temperature applications. Its robust construction ensures reliability and longevity in industries such as chemical processing, marine, and oil and gas. As a leading control valve supplier, we ensure that our ASTM A890 4A Ball Control Valves meet the highest quality standards.
