Product Information
Bellows sealed valve is the valve with bellows as stem sealing components, often used where need strict requirements for stem sealing such as the occasion for high vacuum or nuclear industry. The bellows can eliminate the impact of back pressure fluctuations on the valve and protect springs and other internals from corrosion and leakage by flow media. Instead of stuffing box or worked with stuffing box, the bellows are welded with a cover or other parts by rolling
welding or argon arc welding. Our mainly supply bellows sealed globe valves and bellows gate valves. Our bellow sealed valve is available from ANSI 1500 class up to 2500 pressure.

Product Feature
1. Bellows seal design offers reasonable structure, excellent performance and long service life;
2. Sealing surface welding Co hard alloy, good wear resistance, corrosion resistance and abrasion resistance;
3. Double seal design (bellows + packing) to prevent leakage of media, even if the bellows fail, stem packing will be avoided;
4.Bellows seal stem completely eliminates the common valve stem packing seal aging quickly leak shortcomings to ensure zero stem leakage.
