A105 trunnion-mounted ball valve is a commonly used valve type, whose core component-the ball-is fixed within the valve body by two trunnions (bearings) and sealed against the valve seats. This design enables the ball valve to deliver excellent performance and stability in high-pressure or large-diameter applications. Compared to floating ball valves, trunnion-mounted ball valves require lower torque for opening and closing, can withstand greater pressure differentials, and reduce seat wear, thereby extending the valve's service life. Consequently, it is widely used in industrial fields such as petroleum, natural gas, chemical, and power industries to control fluid flow in pipelines.
