Thread Content
For the upper and lower covers of coking towers as well as the four-way valves, which brand do everyone choose? We are going to issue a tender now; please make some recommendations. Thank you
Four-way valves are usually imported, right? There is a company in Henan that produces four-way valves; our company uses those from this company, and they work fine – so far, there have been no issues!
It’s better to use foreign-made four-way valves; operating them manually is extremely strenuous
Four-way valve: Wilan; Top cover machine: Xiangyang Hangsheng; Bottom cover machine: Z&J
1 Upper and lower covers of coking towers: The current trend is to use slide valves, with the traditional upper and lower covers being phased out gradually. Manufacturers of domestic valves include Jingmen Petrochemical Machinery Factory, Lanzhou Refining Machinery Factory, etc.; similar products may also be available in Xiangfan. It has been maturely applied. Foreign products include Z&J, but they are expensive; they are used at CNOOC Huizhou. In China, most four-way valves used in large-scale coking plants are produced by VELAN. Luoyang Qixin is a company in China that has conducted in-depth research on these valves, and it also uses them in its applications
