API 600 Standard ASTM Steel Stainless Steel Bellow Sealed Globe Valve For Thermic Oil Use

The opening and closing mechanism of this globe valve features a plug-shaped valve disc with flat or conical sealing surfaces. The valve disc moves linearly along the centerline of the valve seat, enabling precise control over various fluid types including air, water, steam, corrosive media, mud, oil, liquid metal, and radioactive substances. This design makes the valve ideal for cutting, regulating, and throttling applications.

The bellow sealed globe valve's key component is the metal bellows, which is automatically welded at the lower end to the valve stem assembly and at the upper end to the connecting plate. This creates a metal barrier between the fluid medium and atmosphere, ensuring zero leakage at the valve stem. Designed specifically for pipelines carrying steam, flammable, explosive, or hazardous media, this valve maintains reliable performance even when bellows are compromised, thanks to its secondary packing system.

• Metal bellows create a barrier between fluid medium and atmosphere, ensuring zero valve stem leakage
• Conical valve disc design with streamlined sealing surface provides superior sealing performance and extended service life
• Dual sealing system (bellows + packing) ensures backup protection and compliance with international sealing standards
• Wide application across chemical, petroleum, electricity, fertilizers, papermaking, and dye industries
• Specifically designed for pipelines carrying flammable, explosive, toxic, and valuable mediums

The bellow sealed globe valve prevents fluid loss, enhancing equipment security and operational safety. With long operational life and minimal maintenance requirements, this valve delivers reliable performance in demanding industrial applications.
