Ball Valve Came Out In The 1950s

  Ball valve came out in the 1950s, with the rapid development of science and technology, production technology and product structure of continuous improvement, in a short period of 40 years, has rapidly developed into a major valve. In the western industrialized countries, the use of ball valves is increasing year by year.

  In China, ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmacy, Water Conservancy, electricity, municipal, steel and other industries, in the national economy occupies a pivotal position. It has a rotation of 90 degrees of action, the plug body as a sphere, there is circular through the hole or passage through its axis.

  Ball valve in the pipeline is mainly used to cut, allocate and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and very small torque can be closed tight. Ball valve is most suitable for switch, cut-off valve use, V-type ball valve. In addition to the electric valve should pay attention to the piping parameters, should pay special attention to its use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, its use of the state affected by its use of the environment is very large. Normally, the electric ball valve, butterfly valve in the following environment use to pay special attention.
