Forged steel check valves with flanged ends are a type of valve commonly used in pipelines to prevent backflow and maintain fluid flow in a single direction. These valves are designed with a flanged end connection, which provides a secure and leak-tight seal when bolted to the pipeline.

The class rating of the flanges on the valve determines the pressure rating of the valve. The three most common class ratings for forged steel check valves with flanged ends are class 150, class 300, and class 600. These ratings indicate the maximum pressure that the valve can withstand and still operate effectively.

The forged steel check valve is a robust and durable design that is well-suited for high-pressure applications. The valve body is typically made from high-quality forged steel, which provides excellent strength and resistance to corrosion and wear.
