GOST 5761-2005 PDF

Full title and description

GOST 5761-2005 — "Valves for nominal pressure at most PN 250. General specifications". This interstate (GOST) standard sets general technical requirements, application limits and normative references for industrial valves with nominal pressure ratings up to PN 250 intended for liquid and gaseous media.

Abstract

This standard specifies general design, material, testing, marking and documentation requirements for pipeline valves intended for service at nominal pressures up to PN 250 and for operating temperatures roughly from 173 K (−100 °C) to 723 K (450 °C). It excludes certain special categories of valves (multistage control, diaphragm, hose, cryogenic, non‑metallic valves and valves for deep vacuum below 0.133 Pa). The standard is intended to be used by manufacturers, purchasers, certification bodies and technical regulators.

Scope

Applies to general‑purpose industrial valves with nominal pressure ratings not exceeding PN 250 and intended for operation with liquid and gaseous media at temperatures approximately from 173 K (−100 °C) up to 723 K (450 °C). The standard does not apply to special valves (multi‑stage control valves, diaphragm valves, hose valves, cryogenic valves, non‑metallic valves) and to valves intended for vacuum below 0.133 Pa (10‑3 mm Hg). It may be used as a basis for certification within national certification systems.

Key topics and requirements

• General design and construction requirements for valves intended for PN ≤ 250 (materials, pressure-containing parts, seats and sealing surfaces).
• Operating temperature and media limits (specified temperature range and media compatibility requirements).
• Strength and tightness testing procedures (hydrostatic and leakage tests) and acceptance criteria.
• Manufacturing and material traceability, heat‑treatment and non‑destructive examination where applicable.
• Marking, packing, technical documentation and type test / routine test records.
• Exclusions and special categories (which require separate normative documents): multistage control valves, diaphragm valves, hose and cryogenic valves, non‑metallic valves and deep‑vacuum valves).
• Normative references to other GOSTs and design/engineering documents (for drawings, tolerances and technical documentation rules).

Typical use and users

Used by valve manufacturers (design and quality departments), procurement and specification engineers, piping and pressure‑equipment designers, certification and conformity assessment bodies, inspection authorities, and end‑users in oil & gas, chemical, power generation, water and general industrial process plants where valves up to PN 250 are required.

Related standards

Replaces earlier national standard GOST 5761‑74. It references and is used alongside other technical documents for drawings and documentation (for example GOST 2.601, GOST 2.602, GOST 9150 and related valve/product standards). For product‑specific or specialty valves, separate GOST/industry standards apply.

FAQ

Q: What is this standard?

A: GOST 5761-2005 is an interstate (GOST) technical standard that establishes general specifications for valves designed for nominal pressures up to PN 250 (general technical requirements, testing, marking and documentation).

Q: What does it cover?

A: It covers general requirements for design, materials, pressure/temperature limits, testing (strength and tightness), marking and documentation for industrial valves up to PN 250, and it explicitly excludes several special valve categories that are covered by other standards.

Q: Who typically uses it?

A: Manufacturers, design and quality engineers, procurement/specification teams, inspection and certification bodies, and plant engineers in industries using pipeline valves (oil & gas, chemical, power, water supply and other process industries).

Q: Is it current or superseded?

A: The standard (GOST 5761-2005) was introduced into effect on 01 October 2008 and remains an acting/interstate standard; it has had amendments/corrections published (including formal amendments announced in 2021 with entry into force dates published by national bodies). Users should check the latest national implementations and published amendments before applying the text.

Q: Is it part of a series?

A: It is part of the corpus of valve and pipeline‑hardware standards within ICS 23.060 and is intended to be used together with product‑specific GOSTs and normative documents (drawings, documentation and testing standards) rather than as a standalone design code for special valve types.

Q: What are the key keywords?

A: Valve; nominal pressure; PN 250; shut‑off valve; pipeline valves; pressure rating; sealing; testing; marking; арматура; клапан.
