The HC44X/SFCV rubber disc check valve is composed of a valve body, valve cover, valve disc, and spring. It is mainly used at the outlet of pipelines in water supply and drainage systems, petroleum, chemical and other industrial sectors to prevent medium back flow. Due to the inclined design of the sealing ring of the rubber disc check valve, the closing time is short, which can reduce water hammer pressure. The valve disc is made of nitrile rubber and steel plate through high-temperature compression, which is resistant to erosion and has good sealing performance. The product structure is simple, and maintenance, repair, and transportation are all very convenient.
