Bellow Seal Globe Valve
The Bellow Seal Globe Valve from Hitech Valves is designed to provide zero stem leakage and long-term sealing reliability in hazardous, toxic, or high-temperature media. Its welded metallic bellows isolate the stem from process fluid, delivering absolute leak-tight performance for critical industrial services.
This valve is widely used in chemical processing, refineries, thermal oil systems, toxic media handling, steam lines, nitrogen plants, pharmaceuticals, and high-purity fluid systems.
