Each subparagraph number refers to a line number on the data sheet. An asterisk (*) indicates information that is to be furnished by the Purchaser. All items without an asterisk are stipulated in either EP 5–3–1 or are to be completed by the Manufacturer. 1) Specify the valve tag identification. 2) Specify the valve size corresponding to the nominal pipe sizes in API 609 or ASME B16.10 where applicable. 3) (*)Specify the valve class per API 609. 4) (*)Specify Category B (see Table 2 of API 609) fire–tested valve meeting the requirements of API 607. 5) (*)Specify the end connection (double flanged, lug– or water–type) and description of mating flanges, see paragraphs 1.2 and 4.2.3 of API 609. 6) (*)Specify the type of companion flange (slip–on, welding–neck, or other) and flange bore or pipe inside diameter, as applicable. The purchaser should verify disc clearances with the valve manufacturer, see paragraph 4.4 or API 609. 7) (*)Specify the operator type, lever or other, see paragraph 4.8 of API 609. 8) (*)Specify materials of construction (see section 5) for the shell, trim (includes: shafts, bushings, seating surfaces on the body and disc, internal keys, pins and screws in contact with the contained fluid), seat retainer, stem pakcing, shaft seal, gland bolting, and gaskets. 9) (*)Specify whether unidirectional or bi–directional flow, see paragraph 4.7.3 of API 609. 10) (*)Specify whether dead end service is required, see paragraph 4.7.4 of API 609. 11) (*)Specify on–off or throttling service, see paragraph 3.4 and 4.8.1 of API 609. 12) Specify any external coating, see paragraph 8.1 of API 609. 13) (*)Specify through drilling or special tapping of lug bolt holes, see paragraph 4.6 of API 609. Bolt holes may be drilled and taped or drilled to pass studs or bolts. 14) Specify allowable gasket–surface interruptions for valve smaller than NPS 6. This needs to be agreed upon between the purchaser and the manufacturer, see paragraph 4.7.2 of API 609. 15) Specify inspection and testing requirements, see section 6. 16) Specify packaging requirements, see EP 5–3–21. 17) Specify Short Pattern face–to–face dimensions for double flanged valves if required. Long Pattern face–to–face dimensions will be supplied for double flanged valves if Short Pattern is not specified, see Table 2 of API 609. 18) Specify electrical continuity if required, see paragraph 4.9 of API 609. 19) Specify whether flanges are integral or welded. Owner’s engineer approval is required for welded flanges, see paragraph 4.2.3 of API 609. 20) Specify drain or bypass connections, if required, see paragraph 4.2.4 of API 609. 21) Specify a lockable device, if required, see paragraph 4.1.3 of API 609. 22) Specify firesafe tested valve design per the current edition of API 607, if desired. 23) (*)Specify the installed orientation of the valve stem. 24) Specify additional notes, if required.
