An API 602 forged valve is a compact, high-integrity heavy-duty valve configuration, available in gate, globe, or check designs, manufactured in strict compliance with the American Petroleum Institute standard for sizes up to 4 inches (NPS 4) and pressure ratings from Class 150 up to Class 1500 LB. Formed through mechanical forging to compress and align the steel's grain structure, this high-performance valve eliminates internal micro-porosity and structural defects to ensure exceptional pressure containment and fracture toughness. Complying with rigorous fugitive emissions and safety tests, it is the universal industry standard for oil refineries, chemical plants, process skids, and compact power generation infrastructure. Procurement specialists can streamline small-bore piping projects by utilizing our digital marketplace to source certified, pressure-tested API 602 forged valves directly from elite manufacturers in China.
