The bellows globe valve forms a metal barrier between the fluid medium and the atmosphere through automatic roll welding, ensuring a zero-leakage design for the valve stem. The interior of the bellows globe valve adopts a bellows structure, with the lower end of the stainless steel bellows welded to the valve stem to prevent process fluid from eroding the valve stem. The plane seal is a face seal, which has better wear resistance.

Compared to ordinary globe valves: Bellows globe valves use bellows to replace packing seals, and the metal sealing structure almost eliminates the possibility of leakage, resulting in no fluid loss, reduced energy waste, and improved safety of factory equipment.

The bellows plane seal is a face seal, which has better wear resistance, longer service life, less maintenance, and lower operating costs. The two have different application scenarios: bellows can be used for toxic and high-level media, while ordinary globe valves are used for ordinary media.
