                  [Valve features]
                  1, floating ball valve lip seal seat, to ensure good sealing performance, small friction coefficient, small operating torque.
                  2, stem anti fly structure: the stem as download type to prevent pressure flying, while after the fire, the formation of metal in contact with the valve stem seal, ensure.
                  3, fire protection and anti-static device (soft sealed floating ball valve).
                  4, with locking device. In order to prevent the misoperation of valve switch, the valve fully open, fully closed position with a lock hole, to ensure that the valve is in the correct position.
                  5, floating ball valve for regular operation, quick opening and closing; relatively small size, light weight, easy maintenance, not limited by the direction of installation; fluid resistance is small, no vibration, noise is small.
