Operating positions for two main-port valves could be either shut (closed) to ensure that no flow in any way undergoes, fully open for max flow, or sometimes partially open to any degree involving. S

Fixed ball valve is mainly used in high pressure large diameter ball valve. According to the installation of the valve seat ring is different from a sphere of fixed valve seat and the ball before the
