What is EN ISO 5752:2012?

EN ISO 5752:2012 is a technical standard that defines the requirements for industrial butterfly valves. This standard provides guidelines for the design, construction, and performance of butterfly valves used in various industrial applications. It specifies the materials, pressure ratings, dimensions, testing procedures, and other important parameters for these valves.

Key Features of EN ISO 5752:2012

EN ISO 5752:2012 covers a wide range of key features that ensure the reliable and efficient performance of industrial butterfly valves. These include:

Valve Size and Pressure Ratings: The standard specifies the sizes and pressure ratings for butterfly valves, ensuring compatibility with different piping systems and applications.

Materials: EN ISO 5752:2012 defines the acceptable materials for the valve body, disc, stem, seat, and other components, ensuring durability and compatibility with the medium being handled.

Design and Construction: The standard outlines the design requirements and construction techniques to guarantee the strength, integrity, and longevity of butterfly valves.

Testing Procedures: EN ISO 5752:2012 provides detailed testing methods to evaluate the performance, leakage, and functionality of butterfly valves under different operating conditions.

Marking and Documentation: The standard also mandates specific labeling and documentation requirements to facilitate traceability and maintenance of butterfly valves throughout their lifecycle.

Benefits and Applications of EN ISO 5752:2012

The implementation of EN ISO 5752:2012 brings several benefits to industries relying on butterfly valves:

Standardization: With a universally accepted set of guidelines, manufacturers can ensure consistency in design, production, and performance of butterfly valves. This facilitates interchangeability and compatibility among different valves from various suppliers.

Reliable Performance: By adhering to the specifications outlined in the standard, butterfly valves offer reliable and consistent operational performance, minimizing the risk of leaks, failures, or downtime. This improves productivity and safety in industrial processes.

Enhanced Quality Control: The rigorous testing procedures outlined in EN ISO 5752:2012 enable manufacturers to conduct comprehensive quality checks on butterfly valves, ensuring that only valves meeting the highest standards are released to the market.

EN ISO 5752:2012 finds applications in various industries, including chemical, oil and gas, water treatment, power generation, HVAC, and many others. It is particularly suitable for applications requiring control and isolation of fluids, where precise flow control and reliable shut-off capabilities are essential.
