API 602 Forged Valve Guide
API 602 compact forged gate, globe and check valves are frequently purchased in Class 800, 1500 and 2500 with socket-weld, threaded or butt-weld ends.
A105N, LF2, F316, F22 and duplex forging grades serve different temperature and corrosion requirements, while bolted, welded or pressure-seal bonnet construction changes the pressure-boundary arrangement.
Before quotation, confirm valve type, bore, pressure class, body/bonnet construction, forging grade, ends, trim, packing, test scope and the project’s documentation requirements.
