Forged Steel Check Valve Full Bore & Reduced Bore

Forged steel check valve class 800 are used to control the flow of fluid in a piping system and prevent backflow. There are two main types of forged steel check valves: full bore and reduced bore.

A full bore check valve has a larger opening compared to a reduced bore check valve. This means that the fluid can flow more easily through the valve, resulting in less pressure drop. The full bore design is often used in high-flow applications where pressure drop is a concern.

On the other hand, a reduced bore check valve has a smaller opening, which can increase the velocity of the fluid passing through the valve. This design is often used in applications where space is limited or where a higher velocity is desired.
