No matter what the valve, the sealing surface most likely to be destroyed, there will be inserted in the process of switching injury, bumps, crushing and other issues. Forged steel ball valve is easy under high pressure so that the two sealing surface atoms penetrate each other, resulting in adhesion phenomenon; if you move the two cover, you will appear adhesion tear, especially in the sealing surface of the higher the case of the more easily occur. If the wrought ball valve bumps or crushes during the closing process, the sealing surface may be partially worn or creased. Medium in the activities of the sealing surface prone to wear and tear, flushing, cavitation consequences, known as "media erosion." This situation often cause local damage, so the quality of the sealing surface must be processed, the erosion of the medium and chemical erosion of the alternating effect, which is the sealing surface will be strongly eroded. In addition to natural damage to the sealing surface, there are man-made damage, man-made damage due to: poor design, poor manufacturing, improper selection, improper installation, improper use and maintenance are not enough, and many other factors; So we must avoid these situations Occurrence, in order to make the ball valve in use without any problems, but also to ensure the life of the ball valve.
We are manufacturer for wheel. Our featured product is 5D Wheel Alignment and it canbe used on all car lifts. This 5D wheel alignment is for mini-scissor lift or we call small scissors lift. The wheel alignment is hang on the ceiling and its camera sight is very large for ultra long wheelbase and track width.
