How is sealing achieved at the stem of a ball valve? Water is constantly dripping from the handle of the ball valve on the water line at home; is it necessary to replace the valve? Is there a good way? What about those in the factory?
The packing plug can be tightened, or even more packing can be added.
Those ball valves with PTFE packing cannot be repaired at home~ Moreover, in factories they are considered wear-and-tear parts that need to be replaced when they break~
