截止阀 Shut-off valve
It is suitable to cut off or connect the pipeline medium in pipelines with various working conditions such as nominal pressure PN16 ~ 420bar (class 150 ~ 2500) and working temperature ≤620 ℃.
Its main structural characteristics:
1. Reasonable product structure, reliable seal, excellent performance and beautiful appearance;
2. The sealing surface is welded with Co-based hard alloy, which has good wear resistance, corrosion resistance, abrasion resistance and long practical life;
3. The valve stem undergoes quenching and tempering and surface nitriding treatment, and has good corrosion resistance and wear resistance;
4. The self-sealing structure is adopted in the middle cavity with nominal pressure ≥250bar (class1500). The sealing performance is enhanced with the increase of pressure to ensure the sealing performance.
5. The valve is provided with an inverted seal structure, which is reliable in sealing.
6. Parts materials, flanges and butt-weld end dimensions can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
