Swing check valve is suitable for pressure PN1.6-16.0mpa, Class 150-2500, working temperature -29-570°C oil, chemical, pharmaceutical, chemical fertilizer, power industry and other working conditions of the pipeline, to prevent media backflow.
Its main structural features are:
1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2. Sealing surface surfacing cobalt-based hard alloy, wear resistance, corrosion resistance, abrasion resistance, long service life.
3. Built-in pin structure, reduce leakage points, reliable use.
4. When the pressure is ≥ 16.0mpa, Class1500, the valve chamber adopts self-tightening sealing structure, the higher the medium pressure, the better the sealing performance.
5. The material of parts and the size of flange and butt welding end can be reasonably selected according to the actual working conditions or user requirements to meet the needs of various projects.
