The 3-piece forged carbon steel ball valve delivers reliable shut-off in high-temperature systems. Made from ASTM A105 forged carbon steel, it offers superior strength and durability up to 560°C. Its extended stem design protects the packing from heat, while socket weld (SW) ends ensure secure, permanent installation in pressurized pipelines. Rated at 800LB, this valve complies with API 607 and is 100% tested per API 598. The soft-seated PTFE ball mechanism ensures zero leakage under normal conditions. Ideal for oil, gas, and chemical processing applications. Trust SFANVALVE for precision-engineered 3-piece forged carbon steel ball valves built for performance and safety.
