3 Piece Flange Trunnion Ball Valve

3 piece flange trunnion ball valve stands out as a high-performance valve, featuring a robust structure that integrates the main valve body, two secondary valve bodies (or flanges), a ball, seats, a stem, and other essential components. By bolting the main valve body to the two secondary valve bodies, a complete and secure valve body structure is formed. This innovative design not only facilitates installation and maintenance but also enhances the valve's pressure and temperature tolerance.

Here are the key highlights of this valve:

Compact Design: The three-piece configuration allows for a more compact overall structure, making it ideal for applications with limited space constraints.

Ease of Maintenance: Thanks to its modular design, the valve can be easily disassembled into multiple parts, significantly simplifying maintenance and part replacement processes, and ultimately reducing maintenance costs.

Exceptional Sealing Performance: The dual seat design ensures two sealing surfaces between the ball and the seats, providing superior sealing in high-pressure, high-temperature, and corrosive environments.

High Flow Capacity: The full-diameter flow path of the ball minimizes fluid resistance, enhancing the valve's flow capacity and ensuring efficient fluid handling.

Versatile Applications: Suitable for a wide range of media, including water, oil, gas, and certain corrosive liquids, this valve finds extensive use in industries such as petroleum, chemicals, power generation, and metallurgy.
