Stainless Steel Bellow Sealed Globe Valve For Steam & Thermic Oil Use
Product introduction:
Bellows sealed globe valve is a type of valve that adopts a bellows sealed design, using automatic rolling welding to isolate fluid medium and atmosphere through the expansion and contraction of the bellows, forming a metal barrier between the fluid medium and atmosphere to achieve zero leakage of the valve stem.
The bellows globe valve has a reasonable structure, reliable sealing, excellent performance, and beautiful appearance. Its valve stem and surface are treated with nitrogen, which has good corrosion resistance and friction resistance; The sealing surface is welded with Co based hard alloy, which has good wear resistance, corrosion resistance, friction resistance, long service life, reduces maintenance frequency, and lowers operating costs. Bellows globe valves have no fluid loss, reduce energy loss, and improve factory equipment safety. The characteristics of bellows globe valves make them an indispensable fluid control equipment in the industrial field, especially in situations that require strict sealing and long-term stable operation.

Product features:
1. Zero leakage: The sealing design of the bellows globe valve can effectively prevent medium leakage, meet strict leakage level requirements, improve equipment safety, reduce maintenance costs, and provide a clean and safe working environment for industrial applications.
2. Double sealing: In addition to bellows sealing, packing sealing is usually equipped to provide double protection, even if the bellows fails, the packing can prevent leakage.
3. Wear and corrosion resistance: The sealing surface of the valve seat and disc is usually welded with cobalt based hard alloy, which has high hardness, corrosion resistance, and wear resistance, extending the service life.
4. Maintenance free: The bellows sealing structure not only eliminates leakage, but also requires no maintenance. If internal components need to be replaced, it is convenient, simple, and fast. All components meet the standards and have strong interchangeability.
5. Easy to operate: The valve stem quenching and surface nitriding treatment has good corrosion resistance and friction resistance, making the valve opening and closing torque small and reducing labor intensity.
6. Strong adaptability: Bellows globe valves are suitable for various media and working conditions, including high temperature, high pressure, flammable, explosive, highly toxic, etc. They are widely used in industries such as petroleum, chemical, pharmaceutical, fertilizer, and power.
Product applications:
Chemical, petroleum, electricity, fertilizers, pharmaceuticals, papermaking, and dye industries.
Especially suitable for pipelines with flammable, explosive, toxic, and valuable mediums.
