Hartz alloy check valve is automatically stop fluid backflow valve. Check valve open valve under the effect of fluid pressure, fluid from the import side of exports down. When the lateral pressure is lower than the export import, more is the disc in the fluid pressure differential \\\\ \\\\ \\\\ \\\\ itself under the action of gravity factors such as shut down automatically to prevent fluid backflow, widely used in power stations, chemical industry, water, etc
