API 6D: This is a commonly used valve design standard in the petroleum and natural gas industry. It stipulates the valve's dimensions, pressure ratings, material requirements, design and manufacturing requirements, etc., ensuring the reliability and safety of valves in petroleum and natural gas transmission pipelines. For example, in high-pressure and large-diameter oil and gas transmission pipelines, the wall thickness and connection methods of valves need to be designed in accordance with the requirements of API 6D to withstand high pressure and prevent leakage.
API 607: This is a standard formulated for the fireproof design requirements of valves. In case of a fire in petroleum and natural gas facilities, valves need to maintain their sealing performance within a certain period of time to prevent the spread of the fire and the leakage of media. If Trunnion Mounted Ball Valves are used in such scenarios, the fire resistance of materials, sealing structures, etc. must comply with the provisions of API 607. For example, seats and seals need to be made of special fireproof materials.
ASME B16.34: It stipulates the basic requirements such as pressure-temperature ratings, dimensions, and tolerances of valves, and is an important basic standard for valve design in the chemical industry, ensuring the safe and reliable operation of valves under different working conditions.
ISO 15848: It focuses on the requirements for fugitive emissions of valves. In chemical production, many media are toxic or harmful to the environment, so valves are required to have good sealing performance to reduce the leakage and emissions of media. The sealing design and material selection of Trunnion Mounted Ball Valves need to meet the standard of ISO 15848 to prevent the leakage of chemical media from harming the environment and personnel.
ASME B31.1: It is mainly used for the design and installation of power piping systems, and there are also corresponding requirements for the selection and installation of valves. In fields such as thermal power generation and nuclear power generation, the design and installation of Trunnion Mounted Ball Valves need to follow the regulations of ASME B31.1 to ensure the compatibility and safety of valves with the entire piping system. For example, the pressure rating and temperature range of valves should match those of the piping system.
IEEE 382: This is a standard for valves used in nuclear power plants, which puts forward strict requirements on aspects such as quality assurance, design, manufacturing, and testing of valves. If Trunnion Mounted Ball Valves are used in nuclear power plants, they need to meet the standard of IEEE 382, including the irradiation stability of materials and the long-term reliability of sealing performance, to ensure the safe operation of nuclear power plants.
EHEDG or 3 - A Sanitary Standards: They have strict requirements on the surface smoothness, material cleanliness, and ease of cleaning of valves. For example, the internal surface of the valve body needs to be smooth without any dead corners for hygiene to prevent the growth of microorganisms; seat and sealing materials should meet the requirements for food and drug safety, and the structural design of the valves should be convenient for disassembly and cleaning. Quick-assembly structures are adopted, etc., to facilitate thorough cleaning and disinfection of the inside of the valves.
FDA-related Standards: The relevant regulations and standards of the U.S. Food and Drug Administration (FDA) have strict requirements on the equipment and materials used in the food and pharmaceutical industries. If Trunnion Mounted Ball Valves are used for fluid control in food and pharmaceutical production processes, the safety and hygiene of materials and the overall design of the valves need to comply with FDA standards to ensure the quality and safety of products.
BS 6364: When valves are used in low temperature environments, such as in the transportation of liquefied natural gas, this standard needs to be followed. The standard has detailed regulations on the material toughness, structural design, and measures to prevent brittle fracture of low temperature valves. It requires that valve materials undergo low temperature impact tests to ensure that they can work normally without cracking in low temperature environments. Meanwhile, there are also special requirements for seat and sealing materials to ensure the sealing performance at low temperatures.
DNV GL Standards: A series of standards formulated by DNV GL (Det Norske Veritas Germanischer Lloyd), covering the requirements for the design, construction, inspection, etc. of various equipment and systems in offshore engineering. When Trunnion Mounted Ball Valves are used in offshore engineering fields such as offshore platforms and ships, they need to meet the relevant DNV GL standards, such as the corrosion resistance, impact resistance, fireproof and explosion-proof performance of valves, to adapt to the harsh conditions of the marine environment and ensure the safe and reliable operation of offshore engineering facilities.
