During The Operating Process:The Benefit of Ball Valves

It is true that the characteristics of ball valves benefit a lot during the operating process. Firstly, it is light with a straightforward structure. The flow would flow smoothly. Secondly, the two discs ensure the tightness. As materials for the sealing surface are commonly various plastics, the favorable leak tightness directs the valve to be widely used, even in the vacuum system. Thirdly, it is easy operated. The handle can be rotated from a long distance within 90 degrees in a short time. And it is certain that the straightforward and active structure is favorable for removal and replacement. Fourthly, the flow would not erode the sealing face as a result of full cut-off or full open. At last, the valve body can be either integral or modular.

Apart from the advantages, there are some aspects that ball valves need to be improved. It is the small range of performing temperatures. Because material of the sealing surface can't bear high temperature. Thus, it is a good chance for the future manufacturers to overcome this shortage by using other materials.

It is certain the specifications for ball valves should regulated according to the GB12237-89, GB/T15185-94,GB8464-87,GB8465.3-87,JB/T53167-94 and JB/Z246-85. It is important to design and produce them accordingly for the consideration of safety and performance. And it is necessary to install and operate the machine based on the instruction. Then, it can function at its best.
