Do You Know The Structural Features Of American Standard Ball Valves
There are many structural features of Control Ball Valve, mainly as follows:
1. Open and close without friction
This feature completely solves the problem of traditional valves affecting sealing due to friction between sealing surfaces.
2. Top-mounted structure
Valves installed on pipelines can be directly inspected and repaired online, which can effectively reduce device shutdown and reduce costs.
3. Single valve seat design
This feature eliminates the problem of abnormal pressure increase in the valve cavity medium affecting the safety of use.
4. Low torque design
For valve stems with special structural design, only a small handle valve can be easily opened and closed.
5. Wedge sealing structure
The valve relies on the mechanical force provided by the valve stem to press the ball wedge to the valve seat for sealing, so that the sealing of the valve will not be affected by changes in pipeline pressure difference.
6. Sealing surface self-cleaning structure
When the ball tilts away from the valve seat, the fluid in the pipeline passes evenly along the ball sealing surface at 360°, which can eliminate the local scouring of the valve seat by high-speed fluid and flush away the accumulation on the sealing surface, playing a self-cleaning role.
