HDDZ Industrial Valve Technology Corporation is committed to R&D and production of high-end valves.
The products include more than 40 series and more than 3000 varieties of full range safety valves, new control valves, gate valves, globe valves, check valves, ball valves, butterfly valves, extraction check valves, three-way valves for high pressure heaters, and high and low pressure bypass valves.
The company's products are used in thermal power, nuclear power, petrochemical, new energy and other fields.
The comprehensive ranking of the company's technological development strength is among the top ten thousand valve plants in China, especially in the field of high-temperature and high-pressure thermal power valves.
Guided by scientific and technological innovation, the company has successively undertaken and completed the localization of supporting valves for 600MW supercritical thermal power units, the development and industrialization of major equipment for 1000MW ultra supercritical thermal power units and other scientific research tasks.
As the most important research participant in the localization of China's ultra (ultra) critical valves, it has undertaken and completed the research and development of all Class II and Class III critical valves. Through the identification organized by the National Energy Administration, most of them have achieved good application performance.
The scale of solar thermal molten salt valve is applied to the molten salt unit of Central Control Delingha Project, successfully replacing imports and breaking the technical monopoly of foreign manufacturers in the field of solar thermal high-end valves.
Among them, molten salt safety valve products won the gold medal of the 9th China (Shanghai) International Fluid Machinery Exhibition and Valve Expo in 2018.
In addition, the company's flagship product, the full range safety valve, won the second prize of the Ministry of Machinery Industry for scientific and technological progress; Electromagnetic discharge device and other products won the national new product award;
The valve series products for ultra (ultra) critical thermal power units have won the Special Prize of Science and Technology of China's Machinery Industry and a number of national patents.
