One-piece ball valve features

1, open and close without friction. This feature is completely solve the traditional valve sealing surface due to impact of friction between the sealing problem.
2, the coat-style structure. On the valve installed in the pipe-line inspection and maintenance directly, can reduce plant parking and reduce costs.
3, single-seat design. Remove the valve in the cavity medium affect the use of abnormal pressure due to safety problems.
4, low-torque design. Special structural design of the stem, just with a small handle to easily open and close the valve.
5, wedge-shaped seal structure. The valve stem is provided by the mechanical force to a seat on the ball and wedge pressure seal against the valve sealing pressure changes of the pipeline, the sealing performance under various conditions have reliable guarantee.
6, the sealing surface of the self-cleaning structure. When the ball away from the seat tilt, the pipeline sphere along the sealing surface of the fluid into a 360
