Forged steel 3‑piece (3PC) threaded ball valves are widely used in oil, gas and high‑pressure fluid export projects. Global industrial projects adopt ASME B16.34 for valve body design and manufacturing, while API 598 governs finished‑valve pressure‑test acceptance. This article walks through the full workflow: forging incoming inspection, precision machining, assembly, hydro‑pneumatic testing and marking, explaining how these two leading standards deliver consistent structural strength, reliable sealing and worldwide spare‑part interchangeability.
