1. In all kinds of valves, ball valve flow resistance is the least, full diameter ball valve open, the ball channel, valve body channel and connecting pipe diameter equal and into a diameter, the medium can flow almost without loss.
2. Ball valve rotation 90° can be fully closed and fully open, open and close quickly. Compared with the gate valve and globe valve of the same specification, the ball valve is small in size and light in weight, which is easy for pipeline installation.
3. Advanced seat: the seat designed with many years of experience in the manufacture of ball valves ensures that the valve is sealed, with low friction coefficient, small operating torque, a variety of seat materials and a wide range of adaptability.
4. Handle with correct switch: using flat head valve stem, the connection with handle will not be misplaced, so as to ensure the switch state indicated by handle and the valve is correct.
5. Lock device: in order to prevent the misoperation of the valve switch, there are locking holes in the fully open and fully closed positions of the valve to ensure that the valve is in the correct position.
6. Stem anti-flying structure: the stem is bottom mounted to prevent the pressure from flying out, and can form metal contact with the valve body after fire, to ensure the valve stem sealing.
7. Ball valve is a ball with a circular through hole as the opening and closing parts, in the stem driven by the ball around the center of the stem for 0~90 degrees of rotation, complete the opening and closing function; It has the characteristics of compact structure and quick switch. It can close the valve and cut off the pipeline medium by turning 90 degrees. The diameter of the ball channel is the same as that of the pipeline, the flow resistance is small and the flow capacity is large. The valve stem is bottom-mounted, which eliminates the accident of the valve stem and ensures the safety of operation.
