FWV Fully Welded Trunnion Side Entry Ball Valve

Size Range: 2”-48”

Pressure Class: ANSI 150-4500
API 2000-15000

    FWV Fully Welded Trunnion Side Entry Ball Valves are specifically designed for gas transportation and storage applications. Their fully welded body construction ensures no potential external leakage at the body and bonnet connection, providing enhanced safety and reliability. Additionally, the forged body offers consistent grain size and uniform thickness, effectively eliminating common defects found in traditional cast valve materials, such as shrinkage and porosity. The entire range of trunnion-mounted ball valves is fire-safe certified by ECM’s Register in compliance with API 607 standards, ensuring top-tier performance and safety.

Main Features and Options:

• Body Construction: Two or three-piece body sections, butt-welded together with no leakage path to the environment.
