Product overview
Floating ball valve opening and closing part (ball) is a valve driven by the valve stem and makes v-turn movement around the axis of the valve stem. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. The ball of the ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end.
Product features
Advanced valve seat: a valve seat designed with many years of ball valve manufacturing experience to ensure valve sealing. Low friction coefficient, small operating torque, a variety of valve seat materials and a wide range of applications.
Handle with correct opening and closing: flat head valve rod is adopted. The connection with the handle will not be misplaced, so as to ensure that the opening and closing state indicated by the handle is consistent with that of the valve.
Locking device: to prevent misoperation of valve opening and closing, there are locking holes at the fully open and fully closed positions of the valve. Ensure that the valve is in the correct position.
Anti flying structure of valve rod: the valve rod is bottom mounted to prevent flying out under pressure. At the same time, it can form metal contact with the valve body after fire. Ensure the sealing of valve rod.
