LF2 Fully Welded Ball Valve

‌Fully Welded Ball Valve‌ refers to a valve where ‌all components are connected by welding‌, without any ‌threaded or flange connections‌. Its ‌integral welded body structure‌ eliminates the possibility of ‌external leakage‌. The ‌ball, seats, stem‌, and other critical components undergo ‌precision machining and assembly‌ to ensure ‌valve stability and reliability.
