GOST R 59553-2021 PDF

Full title and description

Pipeline fittings — Ball valves made of brass. General specifications. (Russian: Арматура трубопроводная. Краны шаровые из латуни. Общие технические условия). This national standard specifies general technical requirements for brass ball valves used in pipeline systems.

Abstract

This standard (GOST R 59553-2021) establishes terminology, material and design requirements, dimensional and connection specifications, marking and documentation rules, testing and quality-assurance procedures, and packaging/transport requirements for brass ball valves intended for use in water, heating, gas (non-aggressive media) and industrial pipeline systems. It is a general technical specification intended for manufacturers, testing laboratories and conformity assessment bodies.

Scope

Applies to brass ball valves used as shut-off or isolating devices in pipeline systems where the transported media are non-aggressive to the valve materials (examples: cold and hot water, steam, liquid hydrocarbons, fuels and lubricants, compressed air, natural gas and other compatible media). The standard covers design, materials, dimensions, connection types, marking, testing and acceptance criteria for general-purpose brass ball valves.

Key topics and requirements

• Definitions and classification of brass ball valves (types, connection forms, nominal sizes).
• Material requirements and recommended brass grades for body, ball and stems; sealing materials and elastomers suitable for intended media and temperature ranges.
• Design and construction rules (seat design, stem sealing, anti-rotation features, requirements for non-disassemblable vs. serviceable designs).
• Dimensional and thread standards for connections (compatibility with national thread and fitting standards), and nominal pressure/temperature ratings for specified sizes.
• Marking, labelling and required documentation (manufacturer identification, nominal size, nominal pressure, material designation, standard number and batch/serial information).
• Testing and quality assurance: hydraulic/pressure tests, leakage classes, functional cycle testing, inspection criteria and acceptance/rejection rules.
• Corrosion protection and surface treatment recommendations (nickel/chrome plating where applicable) and storage/packaging requirements for transport.

Typical use and users

Used by valve manufacturers and designers to ensure product conformity; by procurement and quality departments when specifying valves for plumbing, heating, HVAC, industrial process pipelines, and gas distribution (where permitted); by test laboratories and conformity assessment bodies performing type testing and certification; and by installers and maintenance personnel for selecting compliant components.

Related standards

Typical related documents include older and cross-referenced GOST standards on corrosion protection and thread dimensions (for example GOST 9.302-88 referenced in product listings) and downstream application/installation standards. Certain later GOST R standards for heating and manifold components reference or relate to the ball-valve requirements (examples cited in registries include GOST R 70338-2022 and GOST R 70408-2022). Thread connection norms (e.g., GOST 6357 series for pipe threads) are commonly used alongside this standard.
