Valve industry in national economic development metallurgy butterfly, as an important part of the equipment manufacturing industry, play a very important role. Because China's domestic valve manufacturing level compared with the international advanced level there is still a gap between the butterfly for sale, a lot of high-parameter, high temperature and high pressure, high pound key butterfly valve original has been dependent on imports, such as the European OMAL brand has been a domestic industry valve applications the main choice of objects. To meet the high and low temperatures, strong erosion, long life and other requirements for industrial applications, metal sealing butterfly valve has been a great development. With the high temperature, low temperature resistance, strength, corrosion resistance, strong erosion, high strength alloys in the lock position butterfly valve application, the metal sealing butterfly valve at low temperatures, strong erosion, long life and other industries have been widely applications, there has been large-caliber (9 ~ 750mm), high pressure (42.0MPa), wide temperature range (-196 ~ 606 ℃) of the butterfly valve, butterfly valve so that the technology has reached a whole new level. Seiko butterfly, Gaozhou butterfly valve provided by the Hong Kong Ming Ming Port Valve Co., Ltd., Dongguan. Port Valve Co., Ltd., Dongguan Ming (www.gdmgfm.com) strong, credible, butterfly and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the next port of the valve and you hand into the brilliant, for a better future!
