ISO 17292-2015 pdf free.Metal ball valves for petroleum,petrochemical and allied industries.
ISO 17292 specifies the requirements for a series of metal ball valves suitable for petroleum, petrochemical, natural gas plants, and related industrial applications.
It covers valves of the nominal sizes DN:
— 8,10,15.20,25,32,40,50,65,80,100.150,200,250,300,350,400, 450,500,600;corresponding to nominal pipe sizes NPS:
— ¼,%,½,¾,1,1%.1½,2,2½,3,4,6.8,10,12,14,16,18,20,24;and applies for pressure designations:
— Class 150; 300; 600; 800 (Class 800 applies only for valves with threaded and socket welding end);
— PN 16, 25, 40,63, 100.
It includes provisions for testing and inspection and for valve characteristics as follows:
— flanged and butt-welded ends, in sizes 15 < DN <600 (½ < NPS< 24);
— socket welding and threaded ends, in sizes 8< DN < 50 (¼ <NPS <2);
— body seat openings designated as full bore, reduced bore, and double reduced bore;
— materials.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 DN alphanumeric designation of size common for components used in a piping system, used for reference purposes, comprising the letters DN followed by a dimensionless number indirectly related to the physical size of the bore or outside diameter of the end connection as appropriate
Note I to entry: The dimensionless number following DN does not represent a measurable value and is not used for calculation purposes except where specified in this International Standard. Prefix DN usage is applicable to steel valves bearing PN designations.
3.2 nominal pipe size N PS alphanumeric designation of size common for components used in a piping system, used for reference purposes, comprising the letters NPS followed by a dimensionless number indirectly related to the physical size of the bore or outside diameter of the end connection as appropriate
Note 1 to entry: The dimensionless number may be used as a valve size identifier without the prefix NPS. The dimensionless size identification number does not represent a measurable value and is not used for calculation purposes except where specified in this International Standard. Prefix NPS usage is applicable to steel valves bearing Class designations.
3.3 PN dimensionless alphanumeric designation used to define a maximum pressure/temperature rating applicable to the valve pressure containing shell comprising the letters PN followed by a dimensionless whole number.
Note 1 to entry: The number following the letters PN does not represent a measurable value and is not used for calculation purposes except where specified in this International Standard.
3.4 Class dimensionless alphanumeric designation used in ASME standards to define a maximum pressure/temperature rating applicable to the valve pressure containing shell comprising the letters Class followed by a dimensionless whole number.ISO 17292 pdf download.
