Bellows-Sealed Globe Valve Manufacturer in USA & Canada — SVR Global
SVR Global is a leading Bellows-Sealed Globe Valve Manufacturer in USA and Canada, delivering zero stem leakage, high reliability, and long service life across critical industries. Our valves are engineered with advanced bellows technology that eliminates fugitive emissions and ensures safe operation in demanding environments such as oil and gas, petrochemical, power, LNG, and marine industries.
Function & Working
Bellows-sealed globe valves from SVR Global use a multi-ply welded metallic bellows that creates a pressure-tight seal around the valve stem, preventing leakage to the atmosphere. The bellows is welded to both the stem and the bonnet, forming a secure barrier against hazardous or high-purity media. A secondary packing arrangement provides backup sealing, while the bonnet test port allows condition monitoring. The globe body design ensures precise flow regulation and tight shutoff, making it suitable for both isolation and throttling applications.
