Expansion valve is widely used antibacterial out a whole new vista of development

Origin of the valve as a fluid delivery system control unit as far away as 4000 years ago, first appeared in China , when the valve is an original cork valve , it is used in transporting salt water bamboo pipeline. Since then, with the development of  Trunnion ball valve  to be applied to the valve of the most traditional , ancient, heavy industry - the fermentation industry , the steam , the medium switching, in order to improve people 's working conditions, reduce labor intensity. With excellent brewing Maotai , fen technology in the world famous. With the development , technological advances fermentation technology applications continue to get the extension and expansion of fermented products , more and more  Instrumentation ball valve from the simple fermentation brewing industry extends to the medical and health industry, pharmaceutical antibiotics , hydrocortisone and prednisone and other chemical medicines , antibacterial valve to expand out an  Valve manifolds application of new development world. With large quantities of medicines , modernization and automation of industrial production, are increasingly exposed valve manufacturing technology of antibacterial drugs and pharmaceutical production process requirements of non-adaptive and gaps. Pharmaceutical industry than it made ​​the request of the fermentation brewing industry more scientific and rational , higher, better food and pharmaceutical industries operate GMP requirements .
