ISO 1431 is an international standard that specifies the requirements for gate valves and globe valves, particularly for industrial applications. It covers a range of sizes and pressure ratings, ensuring compatibility and reliability across different systems.
1. Scope: Defines the range of valve sizes and pressure ratings covered by the standard.
2. Design and Manufacture: Specifies detailed requirements for the design and manufacturing of the valves, including body ends, body tappings, and connections.
3. Materials: Outlines the allowable materials and their properties for different components of the valve.
4. Testing and Inspection: Provides protocols for testing and inspection to ensure the valves meet the required performance standards.
5. Marking: Specifies the marking requirements for the valves, including general markings, body markings, and identification plate markings.
• Gate Valves: ISO 1431 specifies a temperature range of -20°C to 200°C for gate valves. This range ensures that the valves can operate reliably in a variety of industrial environments.
• Globe Valves: The temperature range for globe valves under ISO 1431 is also -20°C to 200°C. This range is suitable for applications involving water, steam, and other fluids.
API 6D is a widely recognized standard for pipeline valves, particularly in the oil and gas industry. It covers ball valves, gate valves, plug valves, and check valves with pressure ratings up to Class 2500.
1. Scope: Defines the range of valve sizes and pressure ratings covered by the standard.
2. Design and Manufacture: Specifies detailed requirements for the design and manufacturing of the valves, including body ends, body tappings, and connections.
3. Materials: Outlines the allowable materials and their properties for different components of the valve.
4. Testing and Inspection: Provides protocols for testing and inspection to ensure the valves meet the required performance standards.
5. Marking: Specifies the marking requirements for the valves, including general markings, body markings, and identification plate markings.
• Gate Valves: API 6D specifies a temperature range of -29°C to 121°C for gate valves. This range ensures that the valves can operate reliably in a variety of industrial environments, including those with extreme temperatures.
• Globe Valves: The temperature range for globe valves under API 6D is also -29°C to 121°C. This range is suitable for applications involving hydrocarbons, chemicals, and other fluids.
