The body of Ball valves may be made of metals. Such as: Forged Steel Ball valves, Stainless Steel Ball valves, Alloy Ball valves, Bronze Ball valves, Cast Steel Ball valves and Carbon Steel Ball valves ect. We mainly produces Forged Steel Ball valves according to the standard of API 602 and Stainless Steel Ball valves according to the standard of API 603. We call them API 602 Forged Steel Ball valves and API 603 Stainless Steel Ball valves.The body can also be made of Non-metal Materials. For example, Ceramic Ball valves are erosion-resisting, wear-resisting, cavitation-resisting and antioxidant. Besides that, some Ball valves materials are special, like, Special Alloy Ball valves, Special Steel Ball Valves and Hastelloy Ball valves ect.Transmitting and processing of media that are heavily corrosive, Duplex Stainless Steel Ball valves or Super Stainless Steel Ball valves are usually selected to mitigate the problems for they can work well in the area with corrosive surroundings.
