Welded body trunnion-mounted ball valves use a spherical single weld, and the welding is performed using a fully automatic process. The valve seat sealing structure generally includes a double seal, meaning both upstream and downstream seals. The embedded ring of the valve seat offers excellent corrosion resistance, wear resistance, and good elasticity, providing a high degree of sealing performance.
