Supply Zhejiang Chengyi necked American standard fixed ball valve

r, >High-pressure ball valves came out in the 1990s. With the rapid development of science and technology, the continuous improvement of production processes and product structures, in just a few years, they have rapidly developed into a major valve type. In industrially developed Western countries, the use of high-pressure ball valves is increasing year by year. In my country, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries. , occupying a pivotal position in the national economy.
<:rr, , High-pressure ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used to regulate and control fluids. Among them, the hard-sealed ball valve has a ball core and a metal surfacing of hard alloy. There is strong shear force between the valve seats, which is especially suitable for media containing fibers, tiny solid particles and other media. The multi-way ball valve can not only flexibly control the confluence, divergence, and flow direction switching of media on the pipeline, but can also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in pipelines.
