| Describe： |  |
|||||
| Track ball valve opens and closes without friction. This function completely solves the problem that traditional valves are affected by friction between sealing surfaces. Uploading structure. | ||||||
| Design features： | ||||||
| 1. Single seat design. It eliminates the problem that the medium in the cavity of the valve will affect the safety of operation due to abnormal boosting. 2. Low Torque Design. The valve stem with special structure design can be opened and closed easily with only a small handwheel valve. 3. Wedge seal structure. The valve is sealed by the mechanical force provided by the stem, which presses the ball wedge onto the seat. The sealing performance of the valve is not affected by the variation of pipeline pressure difference and can be guaranteed reliably under various working conditions. 4. Self-cleaning structure of sealing surface. When the sphere tilts away from the seat, the fluid in the pipeline will pass uniformly along the sealing surface of the sphere to 360 degrees. It not only eliminates the local scour of high-speed fluid to the seat, but also washes away the accumulation on the sealing surface, so as to achieve the purpose of self-cleaning. |
