Forged steel check valves are utilized in piping systems to control fluid flow and prevent backflow. There are two main types: full bore and reduced bore check valves.

A full bore check valve features a larger opening, allowing fluid to flow more easily and reducing pressure drop. It is commonly used in high-flow applications where minimizing pressure drop is important.

Conversely, a reduced bore check valve has a smaller opening, which can increase fluid velocity. This design is suitable for limited space applications or when higher velocity is desired.

Forged steel check valves with flanged ends are commonly employed in pipelines to prevent backflow and maintain fluid flow in a single direction. These valves utilize a flanged end connection, ensuring a secure and leak-tight seal when bolted to the pipeline.

The class rating of the flanges on the valve determines its pressure rating, typically classified as class 150, class 300, or class 600. These ratings indicate the maximum pressure the valve can withstand while operating effectively.

Forged steel check valves are known for their robust and durable design, well-suited for high-pressure applications. The valve body is typically constructed from high-quality forged steel, offering excellent strength, corrosion resistance, and wear resistance.

Another variant of forged steel check valves features welded bonnets, designed to control fluid flow and prevent backflow in high-pressure systems. The welded bonnet construction ensures a leak-tight seal, making it ideal for applications requiring high reliability and safety. These valves find widespread use in industries such as oil and gas, power generation, and chemical processing.

The class rating of a welded bonnet forged steel check valve determines its maximum pressure rating, with class 1500 and class 2500 being the most common. Class 1500 valves handle pressures up to 1500 psi, while class 2500 valves can withstand pressures up to 2500 psi.

In welded bonnet forged steel check valves, the valve body and bonnet are joined by welding, providing a strong and secure connection resistant to vibration and thermal expansion. This design eliminates the need for gaskets, which can wear out and require replacement.
