Bronze/Stainless Steel/Copper Electric/Hydraulic/Pneumatic Marine ball valves for Ship Marine Ball valves Bronze/Stainless Steel flanged Ball Valve for ship What's more, The Marine ball valves is carefully polishing and testing before leaving factory to ensure the performance. In addition, Copper&Bronze/Stainless Steel material has longer service life for your pipes&vessel. Classification of flanged ball valves by structure 1 Floating ball valve The ball of a ball valve is floating, and under the action of medium pressure, the ball can generate a certain displacement and tightly press on the sealing surface of the outlet end, ensuring the sealing of the outlet end. The floating ball valve has a simple structure and good sealing performance, While the ball bears all the load of the working medium and is transmitting to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. This structure is widely using for medium and low pressure ball valves 2. Fixed ball valve The ball of a flanged ball valve is fixed and does not move under pressure. Fixing ball valves are equipped with floating valve seats, which move when subjecting to medium pressure, causing the sealing ring to tightly press against the ball to ensure sealing. Usually, bearings are installing on the upper and lower shafts of the
