Steel flanged swing check valves 19s16nzh PN 16 are designed to prevent the backflow of liquids and gases in pipelines and are used in various industries, including oil, gas, and water supply. They are installed on pipelines transporting water, steam, oil products at temperatures up to 425°C. Connected to the pipeline using flanges. Swing check valves 19s16nzh are installed in the working position on a horizontal pipeline with the bonnet facing up, and on a vertical pipeline - so that the disk (valve plate) opens upward. The medium is fed under the disk.
