The A350 carbon steel trunnion ball valve is a specialized ball valve structure featuring a fixed ball secured by two or more trunnions (typically bearings) inside the valve body. Unlike floating ball valves, the ball does not move freely. This design ensures the ball remains in a fixed position during operation, eliminating direct friction between the ball and seats, thereby significantly reducing seat wear and extending valve life. Additionally, the trunnion structure withstands higher pressures, making trunnion ball valves ideal for high-pressure, large-diameter applications.
