Flanged check valve with cast iron body 19ch16br DN350 PN16, GOST

The cast iron 19ch16br check valve is a type of protective check valve and is designed to prevent the backflow of working media in pipeline systems. The valves are manufactured with a flange connection to pipelines. The valves are used when transporting working media - water, steam. The principle of their operation is to create hydraulic resistance to keep the valve open. The closing element of the 19ch16br valve is made in the form of a round disk that can rotate around its axis. The rotary check valve, compared to the lifting one, is less sensitive to environmental pollution and provides stable operation. Another advantage is the ability to control the position of the valve and use compensating or damping devices to prevent hydraulic shocks.
