In the globalized industrial market, valve products need to meet the standard requirements of different countries and regions in order to be applied in a wider range of fields. As a remarkable product, the J-VALVES DN300 PN40 TRUNNION BALL VALVE needs to meet the corresponding specifications in multiple key aspects to achieve compatibility with several important standards such as API 6D, ISO 17292, and GB/T 12237. Now, let's discuss in detail how it meets these standards. Through comparative analysis, you can have a clearer understanding of the secrets within.
· API 6D
Formulated by the American Petroleum Institute, it is an authoritative standard for pipeline valves used in the oil and gas industries. It focuses on the design, manufacturing, inspection, and installation of valves under harsh working conditions, aiming to ensure the reliable operation of valves in complex environments such as high pressure, high corrosion, flammability, and explosiveness. It is widely used in global energy-related industries.
· ISO 17292
This is a standard introduced by the International Organization for Standardization. It comprehensively regulates ball valves from an international perspective, taking into account the general needs of different countries and regions. It emphasizes the universality, performance stability, and adaptability of ball valves to various international pipeline systems, helping ball valve products to circulate without obstacles in global trade.
· GB/T 12237
It is a Chinese national standard that clearly stipulates the technical requirements, test methods, and inspection rules for BALL VALVES in combination with the actual situation of the domestic industry. It focuses on the applicability, ease of operation, and simplicity of maintenance of products in different domestic industrial fields, ensuring that it can meet the usage requirements of numerous domestic engineering projects.
