Power Plant Check Valve

Designed in accordance with ASME B16.34-2013. The valve stem is quenched, tempered, and nitrided, offering high-temperature resistance and excellent corrosion resistance. The body cavity adopts a pressure self-sealing structure; higher internal pressure provides better sealing performance. Adopts a swing-type structure with low flow resistance. The sealing surfaces of the valve seat and disc are overlaid or plasma-spray welded with cobalt-based hard alloy, providing excellent high-temperature resistance, wear resistance, and anti-galling performance.
