Cast Iron Armature - Model 420 Series -Lift Check Valve

The valves are a pipeline fixture for letting out, stopping, and fluid stream regulation, which shutting device moves perpendicular towards the sealing rings (the saddle). This type of lift check valves is used as hold-back devices for the reverse flow of the fluid in case of reducing the pressure before the valve in the pipeline, through which is transported steam, water, air, or non-aggressive fluids, at a pressure not exceeding PN16 and Tmax 200°C. They are implemented as shut-off reverse fluid's streams with decrease a pressure in front of discs. The lift check valves are mounted on horizontal and vertical pipelines.
