Flange ball valve structure is as follows:
1, open and close without friction
This feature completely solve the traditional valve due to the friction between the sealing surface of the problem of sealing.
2, loading structure
The On the pipeline in the pipeline can be directly on-line inspection and maintenance, can effectively reduce the device parking, reduce costs.
3, single seat design
Eliminating the valve medium medium due to abnormal pressure and affect the use of security issues.
4, low torque design
Special structural design of the stem, just with a small hand wheel valve can easily open and close.
5, wedge seal structure
The valve is provided by the valve stem mechanical force, the ball wedge pressure on the valve seat and sealed, so that the valve seal from the pipeline pressure changes in the impact of sealing conditions in a variety of conditions have a reliable guarantee.
6, the sealing surface of the self-cleaning structure
When the ball away from the valve seat, the fluid in the pipeline along the ball sealing surface into the 360 ° evenly through, not only eliminates the high-speed fluid on the seat of the local erosion, but also washed away the sealing surface of the aggregates, to achieve the purpose of self-cleaning.
