    GMK Forged Steel Trunnion Mounted Ball Valve
    A DN80 (3-inch) trunnion-mounted ball valve is a high-performance industrial valve designed for secure,,low-torque, and reliable shut-off in high-pressure, high-temperature, or heavy-duty piping systems, often featuring a fixed ball design for improved stability. These valves typically feature flanged connections (e.g., PN16, PN100) and are suited for oil, gas, and industrial applications. 
    Common Features & Technical Specifications 
    • Size: DN80 (3 inches)
    • Design: Trunnion-mounted, full bore or reduced bore, 2-piece or 3-piece construction, typically following API 6D standards
    • Materials: Typically constructed from Cast Steel (WCB), Forged Steel (A105), or Stainless Steel (AISI 304/316) for enhanced corrosion resistance
    • Pressure Rating: Suitable for high-pressure systems, including PN16 (~232 psi) to high-pressure PN100 applications
    • Temperature Range: Suitable for high-temperature applications, with some models handling up to
      200∘

    What does DN stand for in valve size?
    Diameter Nominal
    DN stands for 'Diameter Nominal'. Put simply, it is a rough translation of mm from imperial sizes, assuming that an inch is 25mm. We refer to a 12″ flange as DN300, when in fact it is 304mm. Please use the table below for your reference and if you have any other questions, please ask the Just Valves team.

    When to use a trunnion mounted ball valve?
    Therefore, in high pressure applications, many people choose trunnion style valves instead of floating ball valves. This is because they're more versatile and can withstand higher pressures and they're easier to operate in such conditions. In addition, most of the time floating ball valves are much smaller.

    What is the size of the 80NB valve?
    3 inches
    The 80NB designation refers to the nominal bore size of the valve, which is approximately 80 millimeters (3 inches). This size is commonly used in medium-pressure pipeline systems for a variety of applications in industries such as water treatment, oil and gas, chemical processing, and power generation.
