Forged Steel Trunnion Mounted Ball Valve

- Design Standard: API 6D
- Structure Length: API 6D; ASME B16.10
- Connection Size: ASME B16.5; ASME B16.47
- Test and inspection: API 598
Forged steel trunnion mounted ball valves are commonly used in industrial applications where high pressure, high temperature, and abrasive or corrosive fluids are involved. Some of the typical applications include oil and gas, petrochemical, chemical, power generation, and water treatment industries.
The forged steel construction of the valve provides high strength and durability, making it suitable for harsh environments and high-pressure applications. The trunnion mounted ball design provides additional support to the ball, which reduces the torque required to operate the valve. This makes it ideal for use in applications where the valve needs to be operated frequently.
The valve also has a floating seat design, which ensures a tight seal even at high pressures. This makes it suitable for applications where a reliable and leak-proof valve is required. The valve can be automated, making it easy to operate and control remotely.
The forged steel trunnion mounted ball valve is a robust and reliable valve that is ideal for use in demanding industrial applications where high pressure, high temperature, and abrasive or corrosive fluids are involved.
