An NPT Forged Valve is a valve crafted with National Pipe Thread Tapered (NPT) connections, adhering to the U.S. standard for tapered threads used on threaded pipes and fittings. These valves are produced through the forging method, which entails heating metal until it becomes soft and shaping it with mechanical forces into the desired form. However, despite their durability, forging defects such as laps, cold shuts, cracks, and inclusions may occur.
