Application of H61Y power station check valve:
The welded check valve is suitable for cutting off or connecting media in pipelines of various working conditions such as petroleum, chemical, hydraulic, and thermal power plants with nominal pressure PN20.0-32.0Mpa and working temperature ≤ 540 ℃ (where P (57) 170V and working temperature 570 ℃). Applicable media include water, oil, steam, etc.

Structural characteristics of H61Y power station check valve:
1. The product design and manufacturing shall comply with the provisions of E101 and JB/T3595-93 standards, with a reasonable structure, excellent performance, and shape.
2. The valve chamber adopts a pressure self tightening sealing structure, and the higher the medium pressure, the better the sealing performance.
3. The two ends of the branch pipe are butt welded to meet different requirements for connecting pipes.
4. The sealing surfaces of the valve disc and seat are made of Stellite cobalt based hard alloy, which is wear-resistant, high-temperature resistant, has good abrasion resistance, and has a long service life.
5. High temperature and pressure resistant components are made of high-quality heat-resistant alloy steel, which is safe, reliable, stable in performance, and has a long service life.
