For butt-welded Ball Valve, there will be no externalleakages and so on.
It will not cause the deformation because of the earthquake and vehicles going through. The pipes are aging resistance.
Buried-welded ball valve can be directly buried in the ground. There is no need to build large valve well. Just set up small shallow wells in the ground so as to greatly save construction costs and time.
According to the pipeline construction and design requirements, the length of the valve and the height of the stem can be adjusted.The machining accuracy of the ball is very high. And the operation is easy and have no bad interference.                                                                                                                  It can prevent the risk from gas explosions. The butt-welded ball valveis a very safe valve.
When you drive the buried-ball valve, the operator does not need to enter the ground, only to operate on the ground. It is very safe and convenient.
