  When selecting resilient seat gate valves for various applications, it's important to consider relevant standards and certifications to ensure that the valves meet industry-specific requirements and standards for performance, safety, and quality.

  Here are some of the key standards and certifications to take into account:

   

  1. American Water Works Association (AWWA): AWWA standards, such as AWWA C509 and AWWA C515, are commonly used for resilient seat gate valves in water and wastewater applications. They provide guidelines for design, materials, and testing to ensure the valves meet the requirements of municipal water supply systems.

  2. American National Standards Institute (ANSI): ANSI standards, including ANSI B16.1 and ANSI B16.10, often apply to gate valves used in various industries. They specify dimensions, pressure ratings, and design criteria for valves.

  3. American Society of Mechanical Engineers (ASME): ASME standards, such as ASME B16.34, are relevant for gate valves used in industrial applications. These standards address design, materials, and testing requirements for gate valves.

  4. International Organization for Standardization (ISO): ISO standards, such as ISO 7259 and ISO 10434, provide international guidelines for gate valves, including those with resilient seats. These standards cover design, testing, and performance specifications.

  5. European Norm (EN): EN standards, such as EN 1171 and EN 1074, are applicable for resilient seat gate valves used in Europe. They define requirements for design, materials, and testing to ensure compliance with European regulations.

  6. NSF International Certification: NSF/ANSI 61 certification is important for valves used in contact with drinking water. This certification ensures that the materials used in the valve construction do not leach harmful contaminants into the water supply.

  7. UL (Underwriters Laboratories) Listing: UL listings are relevant for fire protection applications. Resilient seat gate valves used in fire protection systems should meet UL standards to ensure their reliability in emergency situations.

  8. FM Approval: FM Global provides standards and approval for fire protection equipment. Resilient seat gate valves that meet FM standards are suitable for use in fire protection systems.

  9. CE Marking: For valves used in the European Union, compliance with CE marking and relevant directives is essential to meet safety and performance requirements.

  10. API (American Petroleum Institute) Standards: In oil and gas applications, API standards, such as API 600 and API 602, provide guidelines for gate valves, and these may also apply to resilient seat gate valves in certain scenarios.

  11. Industry-Specific Regulations: Depending on the application, industry-specific regulations and certifications may be required. For example, in the food and pharmaceutical industries, compliance with FDA (U.S. Food and Drug Administration) regulations is necessary.

  It's crucial to consult the specific standards and certifications that apply to the intended use of the resilient seat gate valves. Additionally, working with reputable manufacturers and suppliers who adhere to these standards and certifications can help ensure that you receive valves that meet the required quality and safety criteria for your application.
