ASTM A890 6A Gate Valve

An ASTM A890 6A Gate Valve is made from duplex stainless steel alloy specified by ASTM A890 6A, recognized for its corrosion resistance and strength, particularly in chemical, petrochemical, and marine environments. It operates by lifting a barrier out of the fluid's path, requiring minimal space along the pipe axis and causing minimal flow restriction when fully opened. This alloy's molybdenum content enhances its resistance to pitting and crevice corrosion, making it ideal for high chloride exposure.
