Full title and description

ISO 10631:1994 — Metallic butterfly valves for general purposes. This International Standard specifies general design, material, seating and construction characteristics for metallic butterfly valves (centred or eccentric disc, centred or eccentric shaft; metallic, polymeric, elastomeric or composite seating; lined or unlined body) intended for use in flanged or butt‑welded piping systems for shut‑off, throttling or flow control (nominal diameters DN 40 to DN 2000; nominal pressures PN 2,5 to 50).

Abstract

ISO 10631:1994 defines requirements for metallic butterfly valves for general industrial applications including pressure/temperature rating, face‑to‑face dimensions, seat types and materials, and assembly/testing considerations. The 1994 edition has been withdrawn and later editions (2013, then 2021) provide updated and expanded requirements.

• Edition / version: Edition 1 (1994).
• Number of pages: 11 pages (1994 PDF).

Scope

This standard applies to metallic butterfly valves for general purposes used in flanged or butt‑welded piping systems. It covers valve construction variants (centred/eccentric disc and shaft), seating materials (metallic, polymeric, elastomeric, composite), body/lining/coating options and the applicable nominal diameters DN 40–DN 2000 and pressure ratings PN 2,5–50 under the original 1994 scope. For current projects, users should consult the later revisions (ISO 10631:2013 and ISO 10631:2021) for expanded size and pressure ranges and updated test/inspection requirements.

Key topics and requirements

• Valve type and geometry: centred and eccentric disc/shaft arrangements; face‑to‑face dimensions and mounting arrangements.
• Seating materials and options: metallic, polymeric, elastomeric or composite seats; lined/unlined and coated/uncoated bodies.
• Pressure/temperature ratings: specified PN ranges and guidance for matching materials to rating tables.
• Testing and inspection: functional testing, differential pressure considerations, and conformity to referenced dimensional/pressure standards.
• Referenced standards: cross‑references to flange, material and actuator interface standards (e.g., ISO 7005 series for flanges, ISO 5211 for actuator mounting, ISO 5752 for face‑to‑face series).

Typical use and users

Engineers, valve manufacturers, procurement specialists, piping designers and maintenance teams use ISO 10631:1994 as a baseline specification for metallic butterfly valves in water, utility, industrial process and general piping applications. While useful for historical reference and legacy equipment, professionals specifying new equipment should reference the current edition ISO 10631:2021.

Related standards

Commonly referenced standards in conjunction with ISO 10631 include ISO 5752 (face‑to‑face dimensions / series), ISO 5211 (actuator mounting), ISO 7005 parts 1–3 (metallic flanges), and material standards for castings and steels (e.g., ISO 185, ISO 1083), all of which are cited in the original ISO 10631 text. Newer editions of ISO 10631 also refer to additional application‑specific standards.

FAQ

Q: What is this standard?

A: ISO 10631:1994 is the first edition of the International Standard specifying general requirements for metallic butterfly valves for general purposes (design, seats, materials, dimensions and testing). It was published on 15 April 1994.

Q: What does it cover?

A: It covers metallic butterfly valves with various disc/shaft and seat constructions, intended for flanged or butt‑welded piping systems for shut‑off, throttling or flow control, originally covering DN 40–DN 2000 and PN 2,5–50.

Q: Who typically uses it?

A: Valve manufacturers, mechanical and piping engineers, purchasers and maintenance personnel who design, procure or service butterfly valves, especially when working with metric (DN/PN) systems or legacy equipment specified to the 1994 edition.

Q: Is it current or superseded?

A: ISO 10631:1994 has been withdrawn. It was superseded by ISO 10631:2013 (edition 2, withdrawn) and the current published edition is ISO 10631:2021 (edition 3, published May 2021). For new specifications the 2021 edition should be used. Exact publication dates: ISO 10631:1994 — 15 April 1994; ISO 10631:2013 — September 2013; ISO 10631:2021 — May 2021.

Q: Is it part of a series?

A: ISO 10631 is a standalone standard for metallic butterfly valves but is routinely used together with related ISO standards (for flanges, actuator mounting, face‑to‑face dimensions and materials). It forms part of the broader valve standard family maintained by ISO/TC 153.

Q: What are the key keywords?

A: Metallic butterfly valve, butterfly valve, DN, PN, seat material, actuator mounting (ISO 5211), face‑to‑face (ISO 5752), valve testing, Russian translation/PDF.

Note on Russian PDF availability: Russian‑language PDFs or translations of ISO standards may be offered by national bodies or commercial resellers; several catalogues and standards resellers list a "rus" PDF version of ISO 10631:1994 for purchase. Purchasers should verify the translation origin and copyright status and consider obtaining the current ISO edition where appropriate.
