Ball Valve

China Ball valve

Valve controls the flow of liquids and gases through pipes and tubes. It includes types of butterfly valve, gate valve, check valve, globe valve, ball valve, air vent valve, solenoid valve, pressure reducing valve and others. Here we are going to talk about the ball valve. Ball valves are employed in the pipeline systems. Workers hardly think twice of them. But a fault ball valve in a plane, a machine, or a chemical plant could be no good. Valves must be precision-made and trouble-free. 

China Ball valve firstly appeared in the 1950s. With the rapid development of science and technology as much as continuous improvement of the production process and product structure, ball valve has rapidly developed into one of the main valves in just 40 years. In western industrialized countries, the number of ball valves is on the increase year by year. Now In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceuticals, water conservancy, power, municipal, steel and other industries. It occupies a pivotal position in the national economy.

Ball valves have a 3-piece, threaded or socket-weld body design. In a ball valve, there is a hollowed-out sphere sitting tightly inside a pipe, completely sealing the flow. Its main function is to shut off or on the fluid flow. As the name “ball valve” implies, the ball is with a hole drilled through the body. When the hole in the ball is changed in the same direction as the pipe, this will result in the full flow rate. As the hole in the ball is not the same as the direction of the pipe, the flow rate will be restricted and finally cut off completely when the hole is changed at 90 degrees to the pipe direction. All stainless steel body ball valves come with stainless steel handles.

There is considerable room for expansion in the ball valve industry at the present. The main factors of the expansion include the growing energy demand, sustained increase in global population and urbanization in developing countries, the process of industrialization after the financial crisis. This trend has been growing steadily for years. Currently, the world's major economies have already entered the economic recovery cycle. The ball valve industry was showing a steady upward growth therewith.
