Fully Welded Ball Valve

Robust, maintenance-free valve designed for underground or long-term service in pipeline systems. Unlike bolted-body valves, this valve features a fully welded body structure, eliminating potential leak paths and ensuring excellent strength and durability. It offers reliable sealing even under extreme pressure and temperature conditions, making it ideal for natural gas, oil, and district heating systems. The valve's compact, lightweight design simplifies installation, especially in buried or hard-to-reach locations.

    Benefits

    • Leak-free welded body: No bolted connections mean fewer potential leak points


    • Maintenance-free design: Ideal for underground or inaccessible installations


    • High pressure & temperature resistance: Engineered for demanding service conditions


    • Anti-blowout stem & fire-safe design: Ensures operational safety


    • Corrosion-resistant coating options: Suitable for harsh or corrosive environments


    • Customizable extensions: For underground or remote actuation needs
