Gate valves shall have an obturator which moves in a plane perpendicular to the direction of flow. The gate can be constructed of one piece for slab-gate valves or of two or more pieces for expanding-gate valves. Gate valves shall be provided with a back seat or secondary stem sealing feature in addition to the primary stem seal. 5.1.2 Lubricated and non-lubricated plug valves Typical configurations for plug valves with flanged and welding ends are shown, for illustration purposes only, in Figure 3. Plug valves shall have a cylindrical or conical obturator which rotates about an axis perpendicular to the direction of flow. 5.1.3 Ball valves Typical configurations for ball valves with flanged or welding ends are shown, for illustration purposes only, in Figures 4,5 and 6. Ball valves shall have a spherical obturator which rotates on an axis perpendicular to the direction of flow. 5.1.4 Check valves Typical configurations for check valves are shown, for illustration purposes only, in Figures 7 to 11. Check valves may also be of the wafer type. Check valves shall have an obturator which responds automatically to block fluid in one direction. 5.2 Valve configurations 5.2.1 Full-opening valves Full-opening valves shall be unobstructed in the fully opened position and have an intemal bore as specified in Table 1. There is no restriction on the upper limit of valve bore sizes. Full-opening through-conduit valves shall have a circular bore in the obturator that will allow a sphere with a nominal size not less than that specified in Table 1 to pass. Welding-end valves may require a smaller bore at the welding end to mate with the pipe. 5.2.2 Reduced-opening valves The internal bore of reduced-opening valves shall be less than the internal bore specified in Table 1.

If not specified, the pressure rating as determined in accordance with 6.1 for material at 38"C (100*F) shall be the MPD. The manufacturer shall provide the following data to the purchaser: — the flow coefficient K; — the breakaway thrust or torque for new valve; — the maximum allowable stem thrust or torque on the valve and, if applicable, the drive train. 6.6 Pigging The purchaser shall specify the requirements for piggability of the valves.

Dimensions, tolerances and finishes, including drilling templates, flange facing, spot facing and back facing, shall be in accordance with: — ASME B16.5 for sizes up to and including DN 600 (NPS 24), except DN 550 (NPS 22); — MSS SP-44 for DN 550 (NPS 22); — ASME B16.47 Series A for DN 650 (NPS 26) and larger sizes. 6.7.2 Welding ends Welding ends shall conform to Figures 434.86 (a) (1) and (2) of ASME B31.4 or Figures 14 and 15 of ASME B31.8 unless otherwise agreed. In the case of a heavy-wall valve body, the outside profile may be tapered at 30? and then to 45” as illustrated in Figure 1 of ASME B16.25. The purchaser shall specify the outside diameter, wall thickness, material grade, SMYS and special chemistry of the mating pipe, and whether cladding has been applied. 6.7.3 Special flanges and mechanical joints Other end connections, such as special flanges or mechanical joints, may be specified by the purchaser. 6.8 Pressure relief The manufacturer shall determine whether fluid can become trapped in the body cavity in the open- and/or closed- valve position. If fluid trapping is possible, then valves for gas service, unless otherwise specified by the purchaser, and liquid service shall be provided with an automatic cavity pressure relief. Cavity relief, when required, shall prevent the pressure in the cavity from exceeding 1,33 times the valve pressure rating determined in accordance with 6.1 for material at 38"—C (100%F). External cavity relief valves shall be DN 15 (NPS “/2) or larger. 6.9 Bypass, drain and vent connections Bypass, drain and vent connections and plug entries shall be drilled and threaded unless otherwise specified.

Products stamped with the API Monogram provide observable evidence that they were produced in accordance with a verified quality system and in accordance with an API-recognized, international oil and gas industry product specification. The API Monogram Program delivers significant value to the international oil and gas industry by linking the verification of a supplier's quality system with the demonstrated ability to meet specific product specification requirements. When used in conjunction with the requirements of the API License Agreement, API Specification Q1 Parts One and Two define the program for voluntary licensing of suppliers who wish to provide oil and gas industry products in accordance with an API-recognized international oil and gas industry product specification. API Monogram Program Licenses are issued only after an on-site audit has verified that the licensee conforms with both the quality system requirements described in API Specification Q1 Part One and the requirements of an API- recognized international oil and gas industry product specification. For information on becoming an API Monogram Licensee, please contact API at 1220 L Street, N. W., Washington, DC 20005 or call 202-682-8000. E1 Scope This Annex sets forth the API Monogram Program requirements necessary for a supplier to consistently produce products in accordance with API specified requirements E.2 References In addition to the referenced standards listed in Section 2, this Annex references the following standard: API Specification Q1 For licensees under the Monogram Program, where cited these requirements are mandatory. Referenced standards used by the manufacturer may be either the applicable revision shown in Section 2 and herein, or the latest revision. E.3 API Monogram Program: Licensee responsibilities E.3.1 The requirements for all suppliers desiring to acquire and maintain a license to use the API Monogram shall include: a) The quality system requirements of API Specification Q1, Part One. b) The API Monogram Program requirements of API Specification Q1, Part Two. c) The requirements contained in API recognized product specifications. d) The requirements contained in the API License Agreement.

E.3.3 Each Licensee shall control the application of the monogram in accordance with the following: a) The Licensee shall apply the monogram, license number, and date of manufacture to monogrammed products in accordance with a marking procedure as specified by the applicable API product specification. Where there are no API product specification marking requirements, the licensee shall define the location(s) where this information is applied. b) The monogram may be applied at any time appropriate to the manufacturing process but shall be removed if the product is subsequently found to be in nonconformance with API specified requirements. Products determined to be nonconforming to API specified requirements shall not bear the API monogram. c) Only an API Licensee may apply its monogram. d) The monogram shall be applied at the licensed facility. e) The authority responsible for applying and removing the API monogram shall be defined. E.3.4 Records required by API product specifications shall be retained for the period of time specified therein. Records specified to demonstrate achievement of the effective operation of the quality system shall be maintained for a minimum of 5 years. E.4 Marking requirements These marking requirements apply only to those API licensees wishing to mark their products with the API Monogram. E.4.1 Manufacturers shall mark equipment on the nameplate with “API 6D”, in addition to the marking requirements of Item 15 in Table 12 of Section 11.1. E.4.2 Asa minimum, equipment should be marked with English (Imperial) Units. E.4.3 The API Monogram shall be marked on the nameplate, in addition to the marking requirements of Section 11.1. For valves smaller than DN 50 (NPS 2), the nameplate shall not be omitted, but may be attached to the valve with stainless steel wire. E.S5 API Monogram Program: API responsibilities The API shall maintain, without references to licensees or users, records of reported problems encountered with API monogrammed products produced in accordance with API Specification Q1 and API product standards. E.6 API Monogram Program: User responsibilities The effectiveness of the API monogram program can be strengthened by user reporting problems encountered with API monogrammed products to the API. API solicits information on both new product nonconformance with API specified requirements and field failures (or malfunctions) which are judged to be caused by either specification deficiencies or nonconformance with API specified requirements. Users are requested to report to API problems encountered with API monogrammed products.
