1. 波紋管是波紋管閥門的關(guān)鍵組件，采用自動(dòng)滾焊，焊在閥瓣與閥桿上，確保閥桿部件100%零泄露。
Bellow is the key part of bellow sealed valves,which is welded to both the valve bonnet and valve stem, with automatic roll welding. The metal bellow can keep the stem part 100% no leakage.
2. 雙密封設(shè)計(jì)（波紋管+填料), 波紋管形成第一道,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.
