Present a more advanced triple eccentric butterfly valve is metal seal butterfly valve, valve and seat components for the piece, seat sealing surface layer welding temperature, corrosion resistant alloy material. Multilayer soft stacked ring fixed in the valve plate, this butterfly valve in comparison with the traditional high temperature, easy operation, open and close without friction, closed with the transmission of the torque increases to compensate for sealing heating valves, improving sealing performance and prolong the life of the butterfly's advantage. Suitable for flow adjustment valve. Because of the pressure loss in the pipeline butterfly relatively large brand valves, should be considered to bear the disc media pressure pipeline shutdown ruggedness. Also bronze valves must also be considered to limit the operating temperature at high temperatures endured elastic seat material. The overall length of the structure and the height of the smaller valve opening and closing speed valve, and has good flow control characteristics, Butterfly structure principle most suitable for the production of large diameter valves. When asked to use the butterfly valve to control the flow, the most important is the right size and type of butterfly valves, so that it can be properly and effectively work. High-end valve, the valve out of Hong Kong (certified), Qingyuan valve valve provided by the Hong Kong Science and Technology Co., Ltd., Dongguan Ming. Port Valve Co., Ltd., Dongguan Ming (www.gdmgfm.com) is Dongguan, butterfly leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the next port of the valve leading the staff warmly welcome all inquiries negotiations to create the next port of the valve a better future.
