ASTM A350 LF2 trunnion-mounted ball valve primarily consists of a valve body, ball, stem, trunnion, seals, and other auxiliary components. The core component is the ball, which features a valve port that controls the flow of the medium by rotating the ball. Unlike traditional ball valves, the stem of a trunnion-mounted ball valve is connected to the ball via a trunnion rather than being directly attached to the ball. This design offers several notable advantages:
Enhanced Sealing Performance: The trunnion connection effectively reduces friction between the stem and the ball, minimizing wear and improving sealing performance, especially under high-pressure conditions. Seals are typically made of wear-resistant and corrosion-resistant materials to ensure long-term reliable sealing.
Greater Durability: The trunnion structure enhances the strength and stability of the ball, allowing it to withstand higher pressure and impact forces, thereby extending the valve's service life. The stem also experiences more uniform stress, reducing the risk of bending or deformation.
Easier Maintenance: The design of the trunnion-mounted ball valve facilitates more convenient maintenance of the ball. It is not necessary to disassemble the entire valve; instead, only partial disassembly is required to inspect or replace the ball, saving time and costs.
