Bellows Seal Globe Valve
The Bellows Seal Globe Valve features a stainless steel bellows welded to the valve stem, preventing erosion and ensuring a reliable static seal between the body and bonnet. With dual sealing, it protects against leakage if the bellows fail, while maintaining stable operation and preventing stem vibration. Ideal for steam, flammable, explosive, and toxic media, this valve utilizes advanced metal bellows technology with a long fatigue life, eliminating the leakage issues of traditional stem packing. It enhances energy efficiency, improves safety, reduces maintenance costs, and ensures a cleaner, safer working environment.

Bellows seal globe valves are zero-emission and maintenance-free valves. An uninterrupted metallic barrier is positioned between the process fluid and the external environment. The components subjected to relative movement during valve operation are welded to the ends of a metallic bellows, which absorbs and compensates for the mechanical movement.
As a result, these valves are suitable for a wide range of fluids and are recommended wherever zero-emission performance is required. They help protect the environment and operators' health by preventing fugitive emissions, reduce economic losses caused by fluid or energy leakage, and eliminate the ongoing maintenance costs associated with packing replacement.
In conclusion, bellows seal globe valves are particularly suitable for handling hazardous, flammable, toxic, and explosive media.
- Bellows sealing element: The key component of a bellows-sealed globe valve is the metallic bellows. It is welded between the bonnet and the stem using automatic roll welding technology. The metallic bellows ensures zero leakage at the stem sealing area during operation.
- Disc design: Due to its conical and streamlined design, the disc provides reliable sealing performance and extended service life.
- Double sealing design (bellows + packing): The combination of bellows and packing provides dual protection against leakage, ensuring excellent sealing performance and enhanced safety.
- Grease nipple: A grease nipple is provided to enable direct lubrication of the stem, nut, and sleeve, improving operational smoothness and extending service life.
- Anti-vibration device (DN150 and above): For sizes DN150 and above, a triangular stabilizing device is installed to protect internal components from vibration, reduce noise, and improve structural strength.
- Various disc configurations: Different disc designs are available to suit different operating conditions, including regulating disc, globe-check disc, and soft-seal disc options.
- Ergonomic handwheel: The ergonomic handwheel design provides easier operation and contributes to longer service life.
