Bellows Sealed Globe Valve – China Manufacturer & Supplier

Premium Quality Bellows Sealed Globe Valves from China

As a professional China bellows sealed globe valve manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance bellows sealed globe valves for critical industrial applications where zero leakage and absolute safety are non-negotiable. Our bellows sealed globe valves are engineered to provide zero stem leakage—eliminating fugitive emissions, protecting personnel and the environment, and ensuring compliance with the world‘s most stringent environmental regulations.

Also known as bellows seal stop valves or bellows sealed stop valves, our products utilize a metal bellows—typically constructed from multi-ply stainless steel—that is welded to both the valve stem and bonnet through an advanced automatic roll welding process. This metal barrier forms a hermetic seal between the process medium and the atmosphere, completely eliminating the need for conventional packing around the stem. Unlike standard globe valves that rely on packing materials such as graphite or PTFE—which are subject to wear, aging, and leakage over time—our bellows sealed globe valves deliver maintenance-free, zero-leakage performance throughout their extended service life.

Zero Leakage Through Dual Sealing Design

Our bellows sealed globe valves feature a double seal design (bellows + packing) that provides an unmatched level of safety and reliability. The primary seal is the welded metal bellows, which forms a metal barrier to prevent any external leakage. As a secondary backup, a graphite packing gland is incorporated around the valve stem—if the bellows ever fails, the packing immediately provides a secondary seal to prevent leakage. This redundant sealing system ensures that zero leakage to atmosphere is maintained at all times, even in the unlikely event of bellows failure.
