Bellows sealed globe valve is a globe valve with high performance elastic metal bellows and long telescopic fatigue life. Using bellows seal design, completely eliminate the common valve stem packing seal aging fast leakage shortcomings, not only improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance costs and frequent maintenance, but also provide a clean and safe working environment
Structural characteristics of
1. Double seal design (bellows + packing) If bellows fail, stem packing will also be avoided.
2. Reasonable structure, reliable sealing, excellent performance, beautiful appearance.
3. No fluid loss, reduce energy loss, improve plant equipment safety.
4. The sealing surface surfacing Co based hard alloy, wear resistance, corrosion resistance, friction resistance, long service life, reduce the number of maintenance, reduce operating costs.
5. Rugged bellows seal design ensures zero stem leakage and no maintenance.
6. Stop valve stem conditioning and surface nitriding treatment, has good corrosion resistance and friction resistance;
7. More intuitive indication of valve stem lifting position.
Range of application
Bellows seal globe valve is suitable for petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other industries under various working conditions of the pipeline, used to cut off or put through the pipeline medium.
