The opening and closing of the sanitary quick-install diaphragm valve is realized by the up and down movement of the valve stem driven by the hand wheel. When the valve stem is in the upper position, the spherical diaphragm bends the valve upward to form a conducting state. When the valve stem moves from top to bottom, the valve core is driven to bend the diaphragm, and the diaphragm is forced to close to the seat area or close the pipeline fluid path. It is used to control corrosive or general corrosive media. The surface of the inner cavity of the valve body is not lined or covered with various rubbers to choose from. It is suitable for different working temperatures and fluid pipelines. Mainly used in dairy products, food, pharmaceuticals, beer, cosmetics and other industrial fields. All parts of the sanitary quick-install diaphragm valve in contact with the medium are mirror polished
