China's pump and valve manufacturing industry profits exceeded 49 billion yuan in 2011

At the end of 2011, there were 4,194 manufacturing enterprises for pumps, valves, compressors and similar machinery in China. The total assets of the industry reached 448.98 billion yuan, a year-on-year increase of 21.83%. Data show that: In 2011, China's large-scale industrial enterprises manufacturing pumps, valves, compressors and similar machinery realized main business income of 635.9 billion yuan, a year-on-year growth of 28.41%; and total profit reached 49.968 billion yuan, an increase of 28.71% over the same period of last year.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. The global valve manufacturing industry is mainly concentrated in North America, Europe, Japan, and China. Economically developed regions such as Europe and Japan mainly produce metallurgy, petrochemical, and nuclear power valves. In East Asia and Southeast Asia, such as China and India, the market for drainage valves has been growing faster due to the influence of demand. The number of China's valve companies ranks among the top in the world, but the overall size of domestic water valve companies is relatively small and the industry concentration is low.

Vortex Air Separator

Aone-Best VAS02/05 Vortex Air Separator is used in the circulating water pipe of air conditioning system to separate the air from the system and to discharge the collected air through the Air Release Valve at the top of the system. Through this function, the air in the system can be removed, the pipe resistance can be reduced, the noise can be reduced, the service life of the system accessories can be improved, and the conveying efficiency of the system can be improved.


The working principle of the vertex air separator is to make the water flowing into the separator rotate around the center through its special design structure. Due to the influence of centrifugal force, bubbles and water are separated, gathered at the top of the separator, accumulated to a certain amount and then discharged by the air release valve. Therefore, the higher velocity is beneficial to the separation effect of bubbles and water.
