Super Duplex Butterfly Valve

South American Valve is a leading Super Duplex Butterfly Valve Supplier in Ecuador. A super duplex butterfly valve is a type of butterfly valve that is constructed using super duplex stainless steel. Butterfly valves are quarter-turn valves that are used to control the flow of fluids in a piping system. They are called “butterfly” valves due to the shape of the disc or “butterfly plate” inside the valve, which rotates around a central axis to control the flow.

The use of super duplex stainless steel in the construction of a butterfly valve enhances its properties, making it suitable for applications where corrosion resistance and durability are critical.

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

  • Corrosion resistance: Super duplex stainless steel provides excellent resistance to corrosion, making the valve suitable for applications involving aggressive and corrosive fluids.
  • High-pressure capabilities: Super duplex butterfly valves are designed to handle high-pressure conditions, making them suitable for industries where fluid pressure is a consideration.
  • Durability: The use of super duplex stainless steel ensures the valve’s durability and longevity, even in harsh operating conditions.
  • Versatility: Super duplex butterfly valves are versatile and can be used in various industries, including oil and gas, petrochemicals, chemical processing, water treatment, and more.
  • Quick operation: Butterfly valves are known for their quick quarter-turn operation, which allows for fast opening and closing, making them suitable for flow control applications that require rapid response times.
  • Minimal pressure drop: When fully open, butterfly valves offer a straight flow path, resulting in minimal pressure drop across the valve, which helps optimize system efficiency.
  • Manual or automated operation: Super duplex butterfly valves can be operated manually using a lever or handwheel or automatically with the help of electric, pneumatic, or hydraulic actuators, depending on the application and control requirements.


  • Oil and gas industry: They are used in various oil and gas processes, including pipeline transportation, storage facilities, and refining, where they handle crude oil, natural gas, and other hydrocarbons.
  • Petrochemical and chemical industry: Super duplex butterfly valves are utilized to control the flow of corrosive chemicals, acids, and solvents in different chemical processes.
  • Water and wastewater treatment: They are employed in water treatment plants, desalination facilities, and wastewater treatment plants to regulate the flow of water, chemicals, and wastewater.
  • Marine and offshore applications: Super duplex butterfly valves are suitable for use in marine vessels and offshore platforms, where they can withstand seawater and corrosive environments.
  • Power generation: They find application in power plants to control the flow of water and other fluids in cooling systems, boiler feedwater systems, and other power generation processes.
