Shanghai Dayu Automatic Control Valve Co., Ltd. launched heavyweight 2011 special valve series. Dayu self-control valve company set up a dedicated R & D team, spent a lot of time, energy, financial resources, in recent years have introduced compensated ceramic hemisphere valve, flexible metal seal double-seat sleeve valve, flexible metal seal single seat adjustment Valves and other patented products, the new structure of these products and new technology improvements, innovations in the practical application has been generally praised, recognized. Customer trust has given us the impetus to move forward. At present, all kinds of industrial and mining increasingly complex, the valve requirements are getting higher and higher, the ordinary valve has been far unable to meet customer needs, in some special industries, because the domestic valve can not meet customer requirements, had to spend expensive price To buy imported valves, and the Company has launched a series of new materials under these special series of valves are: titanium alloy valves, nickel-based alloy series valves (Hastelloy, Monel, British Cornell alloy, duplex stainless steel) , Zirconium, tantalum, nickel-aluminum bronze valves and so on. They have good high temperature strength and excellent wear resistance, high temperature resistance, thermal shock resistance, oxidation resistance and excellent resistance to acid, oxidation, valve design standards: GB, American Standard, Germany and the United States, the Japanese standard. Drive mode: manual, electric, pneumatic, worm gear. Its special alloy valve is widely used in chemical industry, aviation military weapons, petrochemicals, marine development, metallurgy, power industry and other industrial areas of acid, alkali, salt harsh corrosive conditions medium. Dayu valve with superior performance, can be comparable to imported valves.
