The 3-piece Fixed Ball Valve Factory specializes in producing high-quality Trunnion Mounted Ball Valves that adhere to API 6D standards. These valves are crafted from forged carbon steel, specifically ASTM A105N, ensuring exceptional strength and durability. With a 16-inch (DN400) diameter and rated for Class 600 LB and PN100 pressure classes, these valves are designed for demanding industrial applications. The RF (Raised Face) flanged ends provide secure and reliable connections.

Trunnion Mounted Ball Valves are engineered for smooth, low-torque operation even under high line pressure, thanks to precision-aligned bearings and a robust trunnion-supported design. Unlike floating ball valves, the ball remains fixed but rotates freely, ensuring reliable performance with reduced wear and superior sealing.
All cast trunnion ball valves are fire-safe certified to BS 6755, API 607, and API 6FA standards, and comply with the latest ASME, API 6D, and BS 5351 specifications. These valves are available in both two-piece split body and three-piece bolted body constructions, offering flexibility for a wide range of industrial applications. Standard features include: Fire-safe construction, Anti-static design, Blowout-proof stem
