Ball valve switch is light, small size, can be made of large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical surface is often closed, not easy to be media erosion, widely used in various industries; In addition the high platform ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Of course, this valve will be based on the material is not the same, the effect is not the same, but the market is relatively speaking, stainless steel is relatively more, some of the requirements of the cast steel is difficult to achieve. |
