GOST 16587-71 PDF

Full title and description

ГОСТ 16587-71 — Клапаны предохранительные, регулирующие и регуляторы давления. Строительные длины. (English title: Safety valves, control valves and pressure regulators — Face-to-face / end-to-end lengths).

Abstract

This intergovernmental (USSR-origin) standard defines the construction (face-to-face / end-to-end) lengths for a range of flanged safety valves, two-seat regulating (control) valves and pressure regulators used in industrial piping systems. It gives dimensional tables, permissible deviations and application limits by nominal diameter and nominal pressure; it excludes lined and special-purpose valves. The standard was introduced in 1973 and was later reissued with amendments.

General information

• Status: Active (ДЕЙСТВУЕТ); restriction on period of validity removed in later reissues.
• Publication date: Introduced 01 July 1973 (designated 1971, introduced by Gosstandart order; reprinted and reissued in later years with amendments).
• Publisher: State Committee for Standards (Gosstandart of the USSR); later reprints published by Изд-во стандартов / Стандартинформ (Moscow).
• ICS / categories: ICS 23.060 (Valves — including pressure regulators, safety valves, check valves).
• Edition / version: Original designation 1971, put into effect 01.07.1973; reissued with Amendments No.1 (1978), No.2 (1982), No.3 (1983); reprints published subsequently (notably 1987 and a collected reprint edition).
• Number of pages: Core text is short — typically shown as 5 pages in some catalogues; certain reprints list 7 pages (varies by edition and publisher).

Scope

The standard applies to flanged safety (relief) valves, flanged two-seat regulating (control) valves and flanged pressure regulators within specified ranges of nominal pressure (Ру) and nominal bore (Dу). Typical scope entries specify flanged safety valves with Ру roughly from 16 up to 320 kgf/cm² and Dу from ~6 to 200 mm; two-seat regulating valves up to Ру ≈ 64 kgf/cm² and Dу from ≈15 to 400 mm; and flanged pressure regulators at Ру ≈ 16 kgf/cm² for Dу from ≈25 to 200 mm. The standard does not cover lined (futered) valves and special-purpose designs.

Key topics and requirements

• Definition of face-to-face (end-to-end) dimensions for specified types of flanged valves and regulators.
• Tabulated construction lengths by valve type, nominal diameter (Dу) and nominal pressure (Ру).
• Permissible dimensional tolerances for construction lengths and relevant mounting interfaces.
• Illustrative schemes / outlines of valve types to which the dimensional tables apply (spring and lever safety valves, two-seat regulating valves, pressure regulators, etc.).
• Exclusions and notes (liners, special-purpose valves) and references to complementary regional recommendations/standards (SEV/СЭВ recommendations and related standards).

Typical use and users

This standard is used by valve manufacturers and foundries producing flanged safety and control valves, plant and pipeline designers specifying valve overall dimensions for piping layouts, procurement departments checking dimensional interchangeability, installation and maintenance engineers ensuring correct mounting and replacement, and certification / inspection bodies verifying compliance with construction length requirements.

Related standards

Corresponds to regional SEV (Council for Mutual Economic Assistance) recommendations such as PC 2377-70 and ST СЭВ 3250-81 (in respect of dimensional coordination). For broader valve dimensional and testing practices consult international documents under ICS 23.060, for example IEC/ISO series on control-valve dimensions and safety-device standards (IEC 60534 series, ISO/EN documents for safety devices and pressure protection).

FAQ

Q: What is this standard?

A: ГОСТ 16587-71 is a USSR-origin intergovernmental standard that sets the construction (face-to-face / end-to-end) lengths for certain flanged safety valves, two-seat regulating valves and pressure regulators.

Q: What does it cover?

A: It covers dimensional (construction) lengths and permissible tolerances for specified ranges of nominal pressure (Ру) and nominal diameter (Dу) for flanged safety valves, control (two-seat) valves and pressure regulators; it excludes lined and special-purpose valves.

Q: Who typically uses it?

A: Valve manufacturers, plant and piping designers, procurement and maintenance teams, and conformity assessment bodies that need standardized overall valve dimensions for design, interchangeability and installation.

Q: Is it current or superseded?

A: The standard is commonly listed as active (ДЕЙСТВУЕТ) in contemporary Russian/ CIS normative catalogues; some editions and reprints include amendments and removal of a time limit on validity. However, for new projects it is common to check whether product-specific or more recent national/international standards (or updated GOST/R standards) are required by the purchaser or regulator.

Q: Is it part of a series?

A: It is a product-specific GOST dealing with valve construction lengths and is referenced alongside other valve standards and regional SEV recommendations (PC 2377-70, ST СЭВ 3250-81). It relates to the broader ICS 23.060 family of valve standards but is not a multipart ISO series itself.

Q: What are the key keywords?

A: Face-to-face length, construction length, safety valve, pressure regulator, control valve, flanged valve, Ду (Dn), Ру (Pn), dimensional tolerance, interchangeability.
