Insulation gate valve industry in national economic development, as an important part of forged steel valve manufacturing equipment, play a very important role. Because China's domestic valve manufacturing level compared with the international advanced level there is still a gap, a lot of high-parameter, high temperature and high pressure, high level of critical valves former pound has been dependent on imports, such as the European OMAL brand has been the main choice of target domestic industry valve applications . If you require the use of flow control valve as soft sealing flange valve, the main choice is the right size and type of valve. Butterfly structure principle is particularly suitable for the production of large diameter valves. There are common butterfly clip-on butterfly valves and flanged butterfly two kinds. Wafer type butterfly valve with stud connection between two pipe flanges, flanged butterfly valve is a valve with a flange with bolts on the valve flange connection on both ends of the pipe flange cryogenic process gate, next to Hong Kong valves, Gaozhou gate valve is 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.
