The knowledge of stainless steel flanged ball valves of Beidou Flange Pipe Fittings Co., Ltd. The stainless steel flanged ball valves are tight and reliable. At present, the sealing surface materials of ball valves are widely used plastics and have good sealing performance. They have also been widely used in vacuum systems. The fluid resistance is small, and the resistance coefficient is equal to that of the pipe section of the same length. The stainless steel flanged ball valve is easy to operate and quick to open and close. It only needs to rotate 90° from fully open to fully closed to facilitate long-distance control. The maintenance is convenient, the structure of the pneumatic ball valve is simple, the sealing ring is generally movable, and the disassembly and replacement are more convenient. 6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium.
