GOST 9698-86 PDF

Full title and description

GOST 9698-86 — "Задвижки. Основные параметры" / "Gate valves. Main parameters". The standard establishes the principal dimensional, operating and classification parameters for industrial gate valves (задвижки) used in pipelines and process equipment.

Abstract

GOST 9698-86 defines the main parameters, ranges and application limits for gate valves with nominal pressures from 0.16 to 25 MPa and nominal diameters from DN 15 to DN 2000. It includes temperature ranges, types of end connections, typical mass and dimensional limits, and references to related normative documents for usage in oil, gas, chemical and power systems. The standard was developed for industrial pipeline valves and is intended to ensure interchangeability, safety and basic performance requirements.

General information

• Status: Active / in force (document database entries list the standard as действующий / effective as maintained in national collections).
• Publication date: Designation year 1986; date of introduction into force 01 January 1988.
• Publisher: State Committee for Standards of the USSR (Gosstandart, Moscow) — original developer attribution; developed by the Ministry of Chemical and Oil Machinery (Минхимнефтемаш). Current national catalogues list the standard under Russian national maintenance.
• ICS / categories: Valves — ICS 23.060 (specifically 23.060.30 Gate valves).
• Edition / version: Original designation GOST 9698-86 (no widely published replacement number shown in national catalogues; databases show it active with later database updates but users should check for any newer national amendments).
• Number of pages: Editions listed in commercial catalogues vary (commonly shown as 7 pages or 11 pages depending on format/translation).

Scope

Applies to industrial pipeline gate valves (задвижки) intended for service at nominal pressures from 0.16 MPa up to 25 MPa and nominal diameters from 15 mm to 2000 mm, for working-fluid temperatures up to about 838 K (565 °C). The standard specifies main dimensional and operating parameter tables, permissible temperature ranges for different pressure classes, connection types (flanged, butt-weld, etc.), and references for testing, marking and documentation. It is intended for general industrial, petrochemical, oil & gas and power applications where GOST parameters are used.

Key topics and requirements

• Nominal pressure (Рy) classes covered: 0.16 MPa to 25 MPa (1.6 to 250 kgf/cm²) and associated parameter tables.
• Nominal diameter (DN) range: DN 15 — DN 2000 with recommended maximum masses and dimensional limits per table.
• Permissible working temperature ranges defined (examples up to 838 K / 565 °C for specific designs); actual temperature limits for a specific valve are to be given in the product technical documentation.
• Types of end connections and mounting (flanged, under-weld, others) and basic flange/face-to-face dimensional parameters.
• Requirements on marking, packaging, storage and transport (basic normative references and marking elements).
• Reference and conformity notes to regional standard ST СЭВ 4366-83 for main parameters used in main oil and gas pipelines (noted in the standard’s normative annexes).

Typical use and users

Used by valve manufacturers, design engineers, pipeline and plant procurement specialists, quality and conformity assessors, maintenance and repair organizations in industries such as oil & gas, petrochemical, power generation, chemical processing and water/steam systems. The standard provides baseline parameters for selection, production and verification of gate valves where GOST-based specifications are required.

Related standards

Commonly referenced and related documents include regional and national valve standards and later general valve specifications such as ST СЭВ 4366-83 (in annex), GOST standards for specific valve classes and materials, and subsequent general specifications for pipeline valves (examples of related documents in databases: GOST 12521-89, GOST 5762-2002 and others addressing detailed technical or material requirements). Users should consult national catalogues for the authoritative list of normative links and any superseding documents.

FAQ

Q: What is this standard?

A: GOST 9698-86 is the Soviet/Russian national standard titled "Задвижки. Основные параметры" (Gate valves. Main parameters) that sets the principal dimensional and operating parameters for industrial gate valves.

Q: What does it cover?

A: It covers the main parameters (pressure classes, nominal diameters, recommended temperature ranges, connection types and mass/dimension limits) for gate valves intended for industrial pipelines and process systems; it also contains references to related normative documents for testing, marking and application limits.

Q: Who typically uses it?

A: Valve manufacturers, system and pipeline designers, procurement and QA specialists, and maintenance organizations in sectors such as oil & gas, chemical, power and utilities where GOST-compliant valve specifications are required.

Q: Is it current or superseded?

A: National databases and commercial standards catalogues list GOST 9698-86 as active (in-force) in those collections; however, later and more detailed GOST or industry-specific standards (for example broader valve technical specifications) exist and may be used in parallel. Users should check the current national standards catalogue or their national standards body for any amendments or formal supersessions before using the standard for certification or design.

Q: Is it part of a series?

A: It is part of the family of pipeline and valve standards (ICS 23.060 series) and is cross-referenced with regional documents such as ST СЭВ 4366-83 and other GOST documents dealing with valve dimensions, materials and testing.

Q: What are the key keywords?

A: Gate valves; задвижки; nominal pressure (Ру); nominal diameter (Dy/DN); flange; butt-weld; temperature limits; valve parameters; GOST 9698-86.
