Welding power station swing check valves
Usages
Welding (GB) Power Station Swing Check Valve is used in the pipelines of petroleum, chemical, water, fire power plant and other systems that nominal pressure is PN20.0 ~ 32.0MPa, work temperature ≤ 540 ℃ ( in which 57170V operating temperature is 570 ℃). Applicable medium: water, oil, steam and so on.
Structural features
1. The product design and manufacture according to the provisions of the E101 and JB/T3595-93 standards, with reasonable structure, excellent performance, beautiful shape.
2. The middle cavity uses pressure self-tight sealing structure, the higher medium pressure, the better the sealing performance.
3. The both ends of branch pipes are butt welded, to adapt to different requirements.
4. The disc and the seat sealing surface use stellite cobalt-based hard alloy bead welding, with wear-resistance, high temperature resistance, good anti-abrasion performance, long service life.
5. High temperature and pressure-resistance components are made of high-quality heat-resistant alloy steel, with safety and reliablity, stable performance, long service life.
