1. No friction between opening and closing.
This feature completely solves the problem that the traditional [wiki] valve [/wiki] affects sealing due to friction between the sealing surfaces. 2. Mounted structure.
Valves mounted on pipes can be checked and repaired directly online, which can effectively reduce device parking and reduce costs. 3. Single seat design.
It eliminates the problem that the cavity medium of the valve affects the safety of use due to abnormal boost. 4. Low torque design.
Special structure design of the stem, just with a small hand to the valve can be easily opening and closing. 5. Wedge-shaped sealing structure.
The valve is based on the mechanical force provided by the stem, the ball wedge is pressed to the seat and sealed, so that the sealing of the valve is not affected by the change in the pipeline pressure difference, in a variety of operating conditions have a reliable guarantee of sealing performance. 6. Self-cleaning structure of the sealing surface.
When the sphere is tilted away from the seat, the fluid in the pipeline is evenly passed along the spherical sealing surface, which not only eliminates the local scour of the seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
In order to reduce the operating torque of the ball valve and increase the reliability of the seal, and the emergence of oil seal ball valve, not only in the sealing surface pressure special lubricating oil, in order to form a layer of oil film, that is, enhance the sealing, but also reduce the operating torque, more suitable for high-pressure large-caliber ball valve.
