This article is about Valve Commodity Code and Valve Code Identification and System. More will be discussed about valve identification tags, valve standards list, HS code for valve parts, o-ring HS code, HS code for gasket, spring HS code, HS code for bearing, pressure gauge HS code and valve codes and standards.
Valve Code Identification and System
This engineering standard describes and establishes the classification system that shall be followed by Company Global Engineering and Manufacturing for manual valves, using commodity codes that are related directly to valve descriptions.
This system is intended to facilitate the preparation of valve summaries, specifications, requisitions, and inventory records. The commodity codes shall be used in global purchase agreements and requisitions to define the items, but are not intended to be used in place of tag numbers. Tag numbers shall be allocated for each valve on a project.
Valve Commodity Code
This standard applies to all worldwide valve specifications written by Mechanical Systems Engineering.
The commodity code system defined herein is the standard classification and coding system that shall be used for all projects that are engineered with worldwide pipe class specifications.

COMMODITY CODES
4.1 This system ensures that valves are uniquely identified by an intelligent code. The commodity code system identifies features and uses of a valve that contribute to the unique code. With such a system it is possible to code the same valve with two different commodity codes; this shall be avoided by searching the valve catalogue before coding a valve.
4.2 Commodity Code Construction
Table 1 – It is about Piping Design Code.
| A | American (ASME B31.3 – not common with European) |
| C | China (PRC) |
| D | German (regulated worldwide) |
| E | European (ASME B31.3 – PED compliant) |
| F | French (regulated worldwide) |
| J | Japanese (regulated worldwide) |
| N | Netherlands [Stoomwezen (regulated worldwide)] |
| W | Worldwide (ASME B31.3) – see Note 2 |
| Z | Special client requirements (project specific) – see Note 3 |
| Table 1 Notes: 1. These designations reflect similar designations used for piping specification classes. 2. The default option should be “W” = Worldwide. Other designations should be used when special code requirements demand variations to the default valve.3. Use of designation “Z” gives a potential for a number of different valves. This will entail the use of different version numbers (see paragraph 4.3.4) | |
Fluid Service Category:
| A | ASU Fluids: Gaseous and liquid nitrogen and argon, liquid oxygen |
| C | Chemicals service |
| E | Electronic service |
| F | Firewater service |
| G | General service |
| H | Hazardous or hydrocarbon service |
| L | Helium |
| N | NACE valves for sour service |
| P | Process air |
| S | Steam service |
| U | Utility service |
| X | Oxidizer service |
| Table 2 Notes: 1. ASU valves will generally have the designation “A.” “X” shall only be assigned by Mechanical Systems Engineering with reference to relevant Oxidizer Standards.2. Designation “A” will also apply to valves in air service when the appropriate cleaning is required. 3. The fluid service category implies a certain cleaning level. For the relationship between fluid service and cleaning refer to 3PI70001 and 3PI70002. Cleaning will be defined on the valve specifications. | |

4.3 Version Number
4.3.1 The final two characters in the commodity code string shall be a numeric version number that can be used to differentiate between different valves that would otherwise have the same commodity code.
4.3.2 This field can be used to define special requirements such as angle globe valves, bellows sealed valves, special trims, full-bore gate and globe valves, schedule for nonstandard butt- weld ends, and other requirements specified in the valve specification.
4.3.3 The initial version of a valve shall have the version number “01“; subsequent variations shall have the next available sequential number. The difference to the initial version shall be recorded in the notes section of the valve specification.
4.3.4 Differences in valves that arise from the use of nonspecific designations shall be coded using different version numbers, and the notes section of the valve specification shall be used to record the special requirements of the valve. In this case, the valve catalog needs to be searched to determine that the required valve has not been coded to date and to ensure that the commodity codes have not been used previously. For example, the use of the “Z” for the project-specific piping design code will result in project-specific commodity codes. Using “Z” on a subsequent project with a different client piping design code will require different version numbers to distinguish these valves from those used on a previous project.
