DIN Ductile Iron GG25 Bellows Sealed 1.6mpa Pressure Flanged Globe Valve

Scope of application

  The bellows stop valve is applicable to pipelines under various working conditions in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other industries. This valve is mainly used to cut off or connect the medium in the pipeline. It is generally not used to regulate the flow.

Structural features

1. double sealing design (bellows + packing) if the bellows fails, the valve rod packing will also be avoided.

2. reasonable structure, reliable sealing, excellent performance and beautiful appearance.

3. no fluid loss, reduce energy loss and improve plant equipment safety.

4. the sealing surface is overlaid with Co based cemented carbide, which has good wear resistance, corrosion resistance, friction resistance and long service life, reducing maintenance times and operating costs.

5. the firm and durable bellows seal design ensures zero leakage of the valve rod and provides maintenance free conditions.

6. the stop valve stem is subject to conditioning and surface nitriding treatment, with good corrosion and friction resistance;

7. valve rod lifting position indication is more intuitive
