Super Duplex Globe Valve

South American Valve is a leading Super Duplex Globe Valve Supplier in Ecuador. A super duplex globe valve is a type of globe valve that is constructed using super duplex stainless steel. Like other globe valves, it is designed to regulate, start, or stop the flow of fluid within a pipeline. The term “globe” refers to the shape of the valve body, which is somewhat spherical.

The main components and working principle of a super duplex globe valve are similar to standard globe valves, but the use of super duplex stainless steel enhances its properties, making it suitable for more demanding and corrosive applications.

South American Valve is a leading Super Duplex Globe Valve Supplier in Ecuador. As with any valve, the specific design and specifications of a super duplex globe valve can vary depending on the manufacturer and the intended application.
