An API 598 Forged Valve is a valve manufactured in accordance with the API 598 standard, which sets forth inspection and testing criteria for resilient-seated, nonmetallic-seated, and metal-to-metal-seated valves. These valves are produced using a forging method, which involves shaping metals and alloys while they are in their solid form. This process typically utilizes heat and industrial-sized tools to apply compressive forces, bending the metals and alloys to the desired shape. Dies are then employed to cut and shape the materials, resulting in the creation of specific valves that meet the standards outlined in API 598.
