性能优势 PERFORMANCE ADVANGATE

1. 波纹管是波纹管阀门的关键组件,采用自动滚焊,焊在阀瓣与阀杆上,确保 阀杆部件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. 双密封设计(波纹管+填料)。波纹管形成第一道金属密封防止泄漏,如果波 纹管失效,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. 

3. 堆焊阀座,即使在恶劣工况下,也能确保可靠的密封。 Overlay welded seat can keep reliable sealing under severe conditions.

4. 人体工程学设计手轮,使用寿命更长,操作轻松便捷且安全可靠。 Ergonomic hand wheel. It provide longer service life and easier Operation.
