GOST 12893-2005 PDF

Full title and description

GOST 12893-2005 — Клапаны регулирующие односедельные, двухседельные и клеточные. Общие технические условия. English title: "Single-seated, double-seated and cage control valves. General specifications." This interstate standard sets general technical requirements, testing and marking rules for industrial control valves with pneumatic (diaphragm or piston) and electric actuators, including provisions for remote-actuated mechanisms and exclusions for diaphragm, hose and manually operated valves.

Abstract

This standard establishes uniform technical conditions for single-seated, double-seated and cage (guided) control valves intended for use in automatic regulation systems handling liquid and gaseous media. It covers constructional requirements, materials, sealing and leakage classes, actuator interfaces (pneumatic and electric), test methods, manufacturer documentation and factory acceptance testing. The standard is intended to ensure interchangeability, safety and reliable performance of regulating valves used in general industrial applications.

Scope

The standard applies to industrial single-seated, double-seated and cage-type regulating valves equipped with pneumatic diaphragm or piston actuators, pneumatic or electric actuators and provisions for remote control. It covers valves intended for liquid and gaseous media in automatic process control systems of general industrial use. The standard does not apply to diaphragm-type and hose valves, manually operated valves or specially excluded gas-transport pipeline valves; additional requirements for export or tropical-climate use are referenced to other normative documents.

Key topics and requirements

• Definitions and classification of single-seated, double-seated and cage control valves, including constructional types and intended applications.
• Materials, welding and mechanical-strength requirements for pressure-containing parts; requirements for corrosion resistance and allowable defects.
• Sealing, leakage classes and acceptance criteria (references to leakage testing standards such as ГОСТ 23866 and specified tightness classes to be shown in product documentation).
• Actuator interfaces and performance: pneumatic diaphragm/piston and electric actuators; requirements for sensitivity (deadband/insensitivity) and actuator-control interaction.
• Dimensional, geometric and manufacturing tolerances; recommended limits for travel (plunger/stem stroke) and deviations unless otherwise specified in design documentation.
• Factory and acceptance tests: hydraulic/pressure tests, leakage tests, functional tests under normal climatic conditions (with referenced climatic standard ГОСТ 15150), instrumentation accuracy requirements for test measurements.
• Marking, documentation and information to be provided with shipments (technical data in product documentation, guarantees of conformity and special notes for systems under supervisory authorities).

Typical use and users

Primary users are valve manufacturers, design and process engineers, procurement/specification teams, testing laboratories and maintenance departments in petrochemical, oil & gas, chemical, power generation and general process industries. Regulatory and inspection bodies refer to the standard when verifying compliance of control valves used in automated technological systems.

Related standards

References and related documents commonly cited with GOST 12893-2005 include the predecessor standard ГОСТ 12893-83 (replaced), leakage and tightness standards such as ГОСТ 23866, climatic/environmental standards for export/tropical service (ГОСТ 26304), and other pipeline/actuator standards used for compatibility and testing. The standard is listed alongside national technical regulations and conformity frameworks where applicable.

FAQ

Q: What is this standard?

A: GOST 12893-2005 is an interstate technical standard that defines general technical requirements, testing and documentation rules for single-seated, double-seated and cage-type regulating (control) valves used in industrial automatic regulation systems.

Q: What does it cover?

A: It covers constructional classification, materials and welding, sealing and leakage requirements, actuator interfaces (pneumatic and electric), nominal dimensions/tolerances, factory and acceptance tests, marking and required documentation; exceptions and additional references (e.g., for tropical climates or special supervisory systems) are explicitly noted.

Q: Who typically uses it?

A: Valve manufacturers, design and process engineers, procurement/specification personnel, testing laboratories, plant maintenance teams and regulatory/inspection authorities in process and heavy industries.

Q: Is it current or superseded?

A: As of available registry entries, GOST 12893-2005 is listed as active / in force (it replaced ГОСТ 12893-83). Implementation and amendment dates vary by registry; check the national standards registry or authorized standards publishers for the latest amendment history.

Q: Is it part of a series?

A: The standard is part of the set of normative documents governing industrial pipeline and valve equipment (ICS 23.060) and is cross-referenced with related GOSTs covering leakage, climatic requirements and actuator/installation standards rather than a numbered multi-part series under the same base number.

Q: What are the key keywords?

A: Regulating valve; control valve; single-seated; double-seated; cage valve; actuator; leakage; factory tests; ГОСТ 12893-2005.
