OEM Valve and fitting

Brass is an alloy composed of copper and zinc, and is an ideal material for manufacturing machined parts (including forged parts). Die casting is abbreviated as forging, which is a casting method in which molten alloy liquid is poured into a press chamber, the cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. Ouzhan's advantage has always been to customize copper valves, that is, valves made of copper, which are industrial parts. The manufacturing process was first developed by Ningbo, Zhejiang in China. In the early 1980s, Ningbo, Zhejiang Province took the lead in developing manufacturing processes, which changed the long history of using cast iron valves in China. In the manufacturing process, the sand casting molding process was first adopted, and the forging process was changed in the early 1990s. Development to the beginning of the 21st century, China has developed into the world's copper valve manufacturing center.Ouzhan has an absolute advantage in producing brass valves, which are sold globally.
