Design and Manufacturing Standards
• ASME B16.34: This standard specifies the design, materials, dimensions, and testing requirements for globe valves, ensuring they meet high standards for pressure containment, shutoff capability, and operational reliability.
• API 600: This standard is specifically designed for gate valves but also provides guidelines for globe valves, ensuring they meet stringent requirements for high-pressure and high-temperature applications.
• Typical Values: Globe valves designed to US standards typically have a fluid resistance coefficient ranging from (Kv)3.5 to 4.5. This value indicates the relative resistance to fluid flow through the valve.
• Impact on Flow: Higher resistance coefficients mean greater pressure drop across the valve, which can affect the overall efficiency of the system. This is particularly important in applications where energy efficiency and operational costs are critical.
German Standards for Globe Valves
Design and Manufacturing Standards
• DIN 3356: This standard specifies the design, manufacturing, and testing requirements for globe valves, ensuring they meet high standards for reliability and performance.
• EN 12266: This international standard provides detailed guidelines for the design and testing of globe valves, ensuring compatibility and interchangeability across different manufacturers.
• Typical Values: Globe valves designed to German standards typically have a fluid resistance coefficient ( Kv ) ranging from 3.0 to 4.0. This range is slightly lower than that of US-standard valves, indicating potentially lower resistance to fluid flow.
• Impact on Flow: Lower resistance coefficients generally result in less pressure drop across the valve, which can improve system efficiency and reduce operational costs. This makes German-standard valves particularly suitable for applications where minimizing fluid resistance is crucial.
