The bellows globe valve is also called the bellows sealed globe valve. Through automatic roll welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure the zero leakage design of the valve stem. Anatomy of the bellows globe valve.
The bellows globe valve adopts a bellows structure inside. The lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from corroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. The double sealing design is adopted. If the bellows fails, the valve stem packing will also avoid leakage. The bellows is welded to the valve stem to maintain stable operating performance and avoid valve stem vibration caused by valve plug vibration.
