Brief Introduction of DIN bellows globe valve:

Bellows globe valve is also called bellows seal globe valve. Through automatic seam welding, a metal barrier is formed between the fluid medium and the atmosphere to ensure zero leakage of the valve stem. The bellows globe valve adopts a bellows structure. The stainless steel lower end of the bellows is welded on the valve stem to prevent the fluid from corroding the valve stem. The high performance elastic metal bellows has a particularly long service life.

Applications of bellows globe valve:

The bellows globe valve is suitable for pipelines under various working conditions in the petroleum, chemical, pharmacy, fertilizer, electric power and other industries, and is used to cut off or connect the mediums.
