Bellow is the key part of bellow sealed valves,which is welded to both the valve

bonnet and valve stem, with automatic rol welding. The metal bellow can keep

the stem part no leakage.

2.雙密封設計(波紋管+填料)。波紋管形成 道金屬密封防止泄漏，如果波

紋管失效，填料可以提供第二道密封。

Double seal design(bellows+packing). Bellow form a metal seal to prevent

leakage, and packing can provide seal if the bellow failed.
