The International Standard Consolidating Small-Bore Valve Requirements for Oil and Gas Service
ISO 15761 fills a specific and useful role in petroleum and natural gas industry valve procurement: it's the international standard specifically covering steel gate, globe, and check valves in the small-bore size range, DN100 (NPS 4) and smaller, that consolidates dimensional, material, testing, and marking requirements for this size category into a single internationally-recognized reference, providing oil and gas industry purchasers with a common specification framework that doesn't require reconciling multiple regional or company-specific small-bore valve standards. This size range — DN100 and below — genuinely represents a distinct valve application category within oil and gas facility piping: small-bore valves handle instrument connections, chemical injection lines, sample points, and utility station isolation duty throughout upstream, midstream, and downstream facilities, applications numerous enough throughout a typical facility that a well-defined, internationally consistent small-bore valve specification meaningfully simplifies both design specification and multi-vendor procurement compared to relying purely on individual national or company standards. ISO 15761 covers gate, globe, and check valve types together within this size scope, reflecting that these three valve types, while functionally distinct (gate valves for on/off isolation, globe valves for throttling/flow control, check valves for backflow prevention), share enough common ground in small-bore petroleum and natural gas service — similar pressure classes, similar end connection types, similar material grade requirements — that a unified small-bore standard serves the industry's procurement needs more efficiently than three entirely separate specifications would.
Forged Components for ISO 15761 Valves
Globe Valve Component Forgings
Forged stem and trim components for ISO 15761 small-bore globe valves used in throttling and flow control service, where precise trim geometry and stem motion control directly affect flow regulation performance.
Check Valve Component Forgings
Forged body and internal component forgings for ISO 15761 small-bore check valves used for backflow prevention on instrument, chemical injection, and utility piping throughout oil and gas facilities.
End Connection and Bolting Forgings
Forged end connection and fastener components matched to the socket-weld, threaded, or small flanged connection type the specific ISO 15761 valve application requires.
Compliance and Quality for ISO 15761 Valve Component Supply
Small-Bore Dimensional and Rating Compliance
Precision manufacturing to ISO 15761's specified dimensional envelope and pressure-temperature rating class for the DN100-and-below size range, verified through dimensional inspection before despatch.

Full Material Test Certification
Material test certificates confirming chemistry and mechanical properties per EN 10204 3.1/3.2, issued as standard for every batch supplied into ISO 15761 valve manufacturer supply chains.
The International Standard Consolidating Small-Bore Valve Requirements for Oil and Gas Service
Small-bore valves rarely receive the same design attention as a facility's large main line isolation valves, but they are genuinely numerous throughout any upstream, midstream, or downstream oil and gas facility — instrument connections, chemical injection points, sample stations, and utility isolation duty all rely on gate, globe, and check valves sized DN100 and smaller, and the sheer volume of these small-bore valve installations across a typical facility is exactly why a well-defined, internationally consistent specification for this category delivers genuine procurement and design value. ISO 15761 fills this role, consolidating small-bore steel valve requirements specifically developed for petroleum and natural gas industry service into a single international standard.
The decision to cover gate, globe, and check valves together under one standard, rather than maintaining three separate small-bore specifications, reflects a practical industry judgment: while these three valve types serve genuinely different functions — on/off isolation, throttling flow control, and backflow prevention respectively — in the small-bore petroleum and natural gas service context, they share enough common ground in pressure class range, end connection types, and material grade requirements that consolidating them under one standard reduces the specification and procurement complexity oil and gas facility designers and purchasers otherwise have to manage across dozens or hundreds of small-bore valve installations per facility.
Forged components remain central to reliable small-bore valve construction under ISO 15761, much as in the small-bore gate valve context ISO 15761's American counterpart standard addresses: stem components must reliably transmit operating torque and thrust across thousands of operating cycles, and body and trim components benefit from forging's grain flow integrity and freedom from porosity, particularly given the often demanding sour service, pressure, and temperature conditions upstream and midstream petroleum and natural gas facility instrument and utility piping frequently involves despite the valve's small physical size.

Frequently Asked Questions
What does ISO 15761 cover?
ISO 15761 is the international standard for steel gate, globe, and check valves in sizes DN100 (NPS 4) and smaller, developed specifically for petroleum and natural gas industry applications, consolidating dimensional, material, testing, and marking requirements for this small-bore size category into a single internationally-recognized reference.
Why does ISO 15761 cover three different valve types under one standard?
Gate, globe, and check valves are functionally distinct — gate valves handle on/off isolation, globe valves handle throttling and flow control, check valves handle backflow prevention — but in small-bore petroleum and natural gas service they share enough common ground in pressure class, end connection type, and material grade requirements that a unified standard serves industry procurement needs more efficiently than three separate specifications.
What size range does ISO 15761 apply to?
DN100 (NPS 4) and smaller. This size range covers instrument connections, chemical injection lines, sample points, and utility station isolation duty — applications that are numerous throughout a typical oil and gas facility despite the individual valve size being small.
Why is a dedicated small-bore valve standard useful for oil and gas industry procurement?
Small-bore valves are used extensively throughout upstream, midstream, and downstream facility piping, and a well-defined, internationally consistent standard for this category simplifies both design specification and multi-vendor procurement compared to relying on multiple national or company-specific small-bore valve standards.
Can you supply ISO 15761 valve components for sour service applications?
Yes. We support NACE MR0175 material compliance documentation for sour service applications, a common requirement across upstream and midstream oil and gas small-bore valve specifications where ISO 15761 valves are typically deployed.
