The HC41X silent check valve is suitable for water supply and drainage pipelines. The valve disc is guided by the central axis at both ends of the inlet, with flexible opening and closing, and can be installed horizontally or vertically. The valve disc is spring loaded, and its quick closing can effectively eliminate water hammer, with good sealing performance and no noise during closing. It has the advantages of small volume, light weight, low fluid resistance, fatigue resistance, and long service life.
