04-SAMSS-047High Performance Butterfly Valves
04-SAMSS-047 is a specification used in the oil, gas, and petrochemical industries. It defines the minimum requirements for a specific type of valve called a butterfly valve. These butterfly valves can be made of steel and have resilient or metal seats. They come in two main types – double flanged and lug type. Additionally, the specification also covers a special type of butterfly valve known as the triple-offset type.
These valves are designed to handle various types of hydrocarbon services, including wet sour liquids or gases. The temperature range for these services can be different for valves with metal seats (from -18 to 425°C) and valves with soft seats (from -18 to 120°C).
For special applications, the specification provides additional requirements in two appendices. Appendix A covers low-temperature services, ranging from -45 to -18°C, and Appendix B covers even lower temperature services known as cryogenic temperature services, which range from -196 to -45°C.
Overall, 04-SAMSS-047 ensures that these butterfly valves are built to meet high-performance standards and are suitable for use in challenging environments, making them a crucial component in the oil, gas, and petrochemical industries.
FAQs about High Performance Butterfly Valves
Answer: The specification covers resilient or metal seated, steel, double flanged, and lug type high-performance butterfly valves, including the triple-offset type, in accordance with API STD 609 Category B.
Answer: These valves are suitable for wet sour liquid or gaseous hydrocarbon services with design temperatures ranging from (a) -18 to 425°C for metal seated valves, and (b) -18 to 120°C for soft seated valves.
Answer: Yes, additional requirements for special applications in low-temperature services from -45 to -18°C are covered in Appendix A, and for cryogenic temperature services from -196 to -45°C are covered in Appendix B.
Answer: The specification does not mention pressure ratings explicitly, but since the valves are categorized as high-performance, they are expected to be suitable for a wide range of pressure levels in various industrial settings.
Answer: API STD 609 Category B sets specific design and testing requirements for butterfly valves used in critical applications. Valves meeting this category are considered to have higher performance and reliability standards, making them suitable for demanding services in the oil, gas, and petrochemical industries.
