High pressure ball valve was invented in 1950s, with the development of continuous improvement of production technology and product structure (especially in the stainless steel series), but also with the requirements of different industries on the ball rising. In a short span of 40 years, has rapidly developed into a mainstream stainless steel valves. In western countries, the developed countries, the use of stainless steel high pressure ball valve is on the increase year by year in China, the ball has been widely used in oil refining, pipeline, chemical, paper, pharmaceutical, water, electricity, municipal, iron and steel industry occupies a pivotal position in the national economy.

High pressure ball valve (stainless steel high pressure ball valve) is mainly used to cut off or connected to the line of medium, can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fiber, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline.

Design and manufacture

Design and manufacture: GB12237, API 6D structure length: GB12221, ANSI B16.10 flange connection: JB/T79, GB9112-9131 ANSI 16.25 pressure temperature rating: ANSI B16.34 E101 test and inspection: API598 E101

Difference

This is from the properties of the product to be divided, of course, and the purpose of the product, as well as the degree of wear to determine. With the development of industry, stainless steel is more and more used by more and more enterprises. From food to space, and stainless steel can not be separated. Therefore, the difference between the two lies in the fact that an ordinary high pressure ball valve, a stainless steel ball valve. From the literal can look at the advantage of the former is that the high number of years.
