ISO 17292:2015

Overview - ISO 17292:2015 (Metal ball valves)

ISO 17292:2015 specifies requirements for metal ball valves used in petroleum, petrochemical, natural gas and allied industries. The standard defines sizes, pressure ratings, end connections, materials, testing and inspection requirements for a broad range of valves. It applies to nominal sizes DN 8–600 (NPS 1/4–24) and pressure designations Class 150, 300, 600, 800 (Class 800 limited to threaded and socket-weld ends) and PN 16, 25, 40, 63, 100. Valve configurations covered include flanged, butt-welded, socket-welded and threaded ends and seat openings of full bore, reduced bore and double reduced bore.

Key technical topics and requirements

• Sizes and pressure classes: DN 8–600 / NPS 1/4–24; Class 150–800 and PN 16–100 (Class 800 applies only to threaded/socket-welded ends).
• End connections: flanged and butt-welded (DN 15–600); socket welding and threaded ends (DN 8–50). Flange standards referenced (ASME B16.5 for Class, EN 1092-1 for PN).
• Valve types and bore options: full bore, reduced bore, double reduced bore.
• Materials and trim: materials for body, ball, stem, seats and seals are specified; seat materials expanded to include modified PTFE and reinforced modified PTFE. Provision for low-temperature and sour-service (H2S) considerations, with purchaser option to require ISO 15156 or NACE MR0103 compliance.
• Design safety features: anti-static design, anti‑blow‑out stem, gland and bolting requirements, ball-stem construction and means to prevent trapped-center cavity overpressure (purchaser option).
• Testing, inspection and marking: pressure/shell tests, closure tightness tests, inspection extents, identification plate content and required marking for traceability. ISO 5208 (pressure testing) and ISO 5209 (marking) are referenced.
• Purchaser options: long/short face-to-face dimensions, locking devices, export packaging, recommended spare parts identification.

Practical applications and users

ISO 17292 is intended for:

• Valve manufacturers and designers specifying engineered metal ball valves for upstream, midstream and downstream facilities.
• Plant engineers and procurement teams in petroleum, petrochemical and natural gas operations selecting valves to meet safety, pressure-temperature and compatibility requirements.
• Quality, inspection and maintenance personnel performing acceptance testing, commissioning and periodic inspection.
• Pipeline and process equipment specifiers ensuring interchangeability and compliance with industry flange/thread standards.
