API 6D DUPLEX Stainless Steel Ball Valve

Aug 22, 2025 Leave a message

Duplex steel ball valves are primarily constructed of duplex stainless steel, offering high strength and resistance to chloride ion corrosion. They offer low fluid resistance, rapid opening and closing (full opening and closing is achieved with a 90° rotation), and excellent sealing performance. The valve seat is constructed of elastic materials such as polytetrafluoroethylene, and the sealing force increases with increasing media pressure.
