Extended-shaft ball valves operate similarly to standard ball valves but have longer stems that extend beyond the insulation layer, allowing for easier operation and maintenance even when the valve is insulated. An Extended Shaft ball valve, designed for low-temperature applications, features a longer stem to prevent freezing and ensure smooth operation in cold environments. Its robust construction and specialized materials offer reliable performance, making it ideal for cryogenic systems, LNG terminals, and other industrial settings requiring precise flow control under extreme temperature conditions.
