Within the vast landscape of power plants, valves reveal their significance in steam systems, cooling circuits, and fuel supply lines. They become integral players, ensuring the efficient operation of turbines and boilers.

Mining and Metallurgy:

In the rugged terrain of mining operations, valves take center stage, managing the flow of slurries, газы, и химикаты. Their indispensable role extends to metal extraction and refining processes, contributing to the core of these operations.

Pulp and Paper Industry:

The intricate dance of valves continues in the pulp and paper industry, where they facilitate the regulated flow of liquids and gases. Their role in this sector is vital, ensuring the seamless operation of processes critical to paper production.

Purpose and Scope of Standards

From my perspective, standards offer a consistent framework governing the design, manufacturing, and testing of valves. This uniformity ensures that valves from different manufacturers adhere to recognized criteria, fostering reliability and interoperability.

In my exploration, I’ve found that common standards establish a universal language for specifications, simplifying international trade. Manufacturers can produce valves that meet globally recognized criteria, streamlining cross-border transactions.

Global Scope of Industrial Valve Standards:

Organizations like the International Organization for Standardization (ИСО) and the American National Standards Institute (АНСИ) play a pivotal role in shaping global standards for industrial valves. These standards serve as reference points for manufacturers across the globe.

Different regions may have specific standards influenced by local regulations and industry practices. Однако, efforts are underway to align regional standards with international norms to ensure a cohesive global approach.

Major International Standards Organizations

International Organization for Standardization (ИСО):

The ISO is a preeminent global standards-setting body. It develops and publishes international standards that encompass a wide range of industries, including industrial valves.

ISO standards provide a common language and set of criteria for manufacturers, ensuring consistency and interoperability across borders. ISO standards related to industrial valves cover aspects such as design, материалы, and testing procedures.

American National Standards Institute (АНСИ):

ANSI oversees the development of standards for a variety of industries, including valves. It serves as the national standards body for the United States.

ANSI facilitates the development of consensus-based standards, ensuring that industry stakeholders, experts, and government representatives contribute to the standardization process. ANSI standards often align with global norms.

ANSI collaborates with international standards bodies, such as ISO and the International Electrotechnical Commission (IEC), to harmonize standards and promote global consistency. It actively engages in partnerships to enhance the adoption of standards.

European Committee for Standardization (CEN):

CEN develops standards for European countries, fostering harmonization and ensuring a common framework for industries, including the manufacturing of industrial valves.

CEN standards contribute to the safety, quality, and efficiency of industrial valves within the European market. They address various aspects, from performance requirements to testing methods.

CEN collaborates with other regional standards organizations and participates in international standardization efforts. This collaboration enhances the alignment of European standards with global counterparts.

International Electrotechnical Commission (IEC):

IEC focuses on developing international standards for electrical, electronic, and related technologies. While not specifically centered on valves, it may contribute to standards related to valve automation and control systems.

IEC standards may intersect with industrial valve standards, particularly those related to valve actuators, control systems, and associated electrical components.

IEC collaborates with ISO to develop standards that integrate both electrical and mechanical aspects, ensuring a comprehensive approach to industrial products, including valves with electronic components.

Deutsches Institut für Normung (ОТ):

DIN is the German Institute for Standardization, contributing to the development of standards for various industries, including the manufacturing of industrial valves.

DIN standards are widely recognized and adopted in Germany and beyond. They cover aspects such as materials, dimensions, and testing procedures for industrial valves.

DIN collaborates with international standards bodies to align its standards with global norms. Its participation in the standardization process ensures that German expertise contributes to the development of comprehensive standards.

Valve Types and Classification

Задвижки:

Description: Gate valves control the flow of fluid by raising or lowering a gate (a wedge-shaped disc) into or out of the flow path. They provide a tight seal when fully closed.

Приложения: Commonly used in on/off applications where a full flow or complete shut-off is required. Found in water and wastewater systems, нефте- и газопроводы, и более.

Globe Valves:

Description: Globe valves have a disc (plug or disc) that moves perpendicular to the flow path, controlling the fluid by changing the size of the flow opening.

Приложения: Suitable for throttling or regulating flow. Commonly used in industries such as chemical processing, petrochemicals, и производство электроэнергии.

Шаровые краны:

Description: Ball valves use a spherical disc (the ball) to control flow. When the ball is positioned parallel to the flow, it allows for full flow; when perpendicular, it blocks the flow.

Приложения: Widely used in various industries due to their versatility. Common applications include water supply systems, gas pipelines, и химическая обработка.

Butterfly Valves:

Description: Butterfly valves have a disc that rotates around a shaft in the center of the valve. The disc’s rotation controls the flow by either aligning with the flow path or blocking it.

Приложения: Ideal for large-diameter pipelines and applications where quick and efficient control is required. Used in HVAC systems, очистка воды, and certain industrial processes.

Check Valves:

Description: Check valves allow flow in one direction only, предотвращение обратного потока. They typically have a flap, disc, or swing mechanism that opens in the direction of flow.

Приложения: Commonly used to prevent backflow in water and wastewater systems, химическая обработка, и нефте- и газопроводы.

Control Valves:

Description: Control valves regulate fluid flow by varying the size of the flow passage. They are equipped with actuators for precise control.

Приложения: Integral in processes requiring precise control, such as in chemical manufacturing, электростанции, and refining.

Safety Valves:

Description: Safety valves automatically release pressure when it exceeds a predetermined level, protecting equipment from overpressure.
