Our Production Process









Brass raw materials are bought from local suppliers in forms of brass bars, frequently used are HPb57-3, CW617N, CW602N(DZR).







Brass bars are cut into smaller pieces with different sizes according to order requirements, heated with natural gas flare to 650~825℃.







The heated brass bars are forged by forging machines, Outcomings are semi-finished rough brass valve bodies.







The rough valve bodies are trimmed and cut off unnecessary parts.







The rough valve bodies are washed with sanding machines, to clean the dirty and oils during production.







The rough bodies are machined by CNY machineries for threads and dimensions.







The machined valve bodies are nickel- or chrome-plated, this step is outsourcing because of government policy on environmental protection.







All the spare parts are assembled for finished brass valves, packed in inner boxes and outer cartons.







The brass valves are ready for delivery after final finished goods quality inspection.
