Why is the wrench of the ball valve easy to break with the valve body?

1, the material of ball valve wrench is generally inferior to that of valve body, and the workmanship is rough.

2. If the ball valve is not opened and closed for a long time, due to the influence of air and pipeline medium, the ball, gasket and valve body will stick together and the friction will increase. At this time, if the wrench is forced quickly, the ball valve will be difficult to open and the handle will be stressed too much.
