An ASTM A890 6A Ball Valve is a flow control device made from duplex stainless steel per ASTM A890 6A standards, known for its superior corrosion resistance and strength. The valve operates using a hollow, perforated, and pivoting ball. It opens when the ball's hole aligns with the inlet and closes when pivoted 90 degrees by the handle, effectively blocking the flow. Ideal for chemical, petrochemical, and marine environments, its molybdenum content enhances resistance to pitting and crevice corrosion in high-chloride conditions.
