The initial products produced by BOPIN were accessories for ball valves, mainly consisting of valve balls, valve stems and valve seats, supplying accessories to our local ball valve manufacturers. After years of experience, the company has increased the production workshops of finished forged steel ball valves, metal seated ball valves, and trunnion mounted ball valves. And in order to meet the diverse valve needs of most customers, production workshops for bellows sealed valves, eccentric butterfly valves, and concentric butterfly valves have been established separately.
