We mainly focus on two-piece and three-piece stainless steel ball valves, but we also provide a variety of three-piece pinch valves, and can manufacture flange ends and butt weld ends according to requirements. Our ball valves are made of high-grade 316 stainless steel. The two-piece stainless steel valve is quickly becoming the most widely used threaded ball valve, replacing the traditional brass ball valve due to its cost and durability. Dealers please call for special offers.
