Highlight: Bellows Globe Valve

Product introduction:

Bellows gate valves are primarily gate valves that use bellows as the stem sealing element. They are commonly applied in

scenarios with strict stem sealing requirements, such as high-vacuum environments and nuclear industries. By replacing the

packing gland in ordinary valves or using it in conjunction with the packing gland, bellows can eliminate stem leakage,

preventing the spillage of radioactive materials or precious metals, or maintaining high vacuum. The bellows expand and

contract with the stem's movement, and their maximum working pressure is determined by the pressure resistance and

fatigue strength of the bellows.

Product features:

1. The product features a reasonable structure, reliable sealing, excellent performance, and an aesthetically pleasing design.
2. The sealing surface is overlaid with cobalt-based hard alloy, offering excellent corrosion resistance, wear resistance, and a long service life.
3. The valve stem undergoes quenching and tempering treatment as well as surface nitriding, ensuring good corrosion and wear resistance.
4. Double-sealing design enhances performance.
5. The valve stem lifting position indicator provides intuitive visualization.
6. Material selection for components, as well as flange and butt-welding dimensions, can be rationally configured according to actual working conditions or user requirements to meet various engineering needs.
