The API 6D A105 Fully Welded Ball Valve (DN1200) is a high-capacity pipeline valve designed for natural gas and oil transmission. Its fully welded body eliminates potential leak paths through bolted joints, ensuring maximum structural integrity for underground or subsea burial. Built from A105 forged steel, this DN1200 (48") valve features a trunnion-mounted ball for manageable torque and Double Block and Bleed (DBB) capability to ensure safe, bubble-tight isolation in critical grids.
