In industrial fields such as petroleum, natural gas, and chemical engineering, the pressure-bearing performance of valves is one of the key factors to ensure the safe operation of systems. API 6D and ASME B16.34 are two important standards widely applied in the design and manufacturing of valves. This article will conduct a comparative analysis on the pressure-bearing performance differences between trunnion ball valves and gate valves under these two standards, helping engineers and purchasers better select valves suitable for their application scenarios.

In the liquefied natural gas (LNG) industrial chain, low-temperature valves are crucial equipment to ensure the safe and stable operation during the processes of production, storage, transportation, and utilization. Among them, trunnion ball valves have been widely used in LNG low-temperature working conditions due to their advantages such as simple structure, good sealing performance, and low flow resistance. However, due to the particularity of LNG working conditions, valves are required to maintain reliable performance at extremely low temperatures, which imposes extremely high requirements on valve selection and manufacturing processes. This article will focus on discussing the key points for selecting trunnion ball valves under LNG low-temperature working conditions and the technological breakthroughs in cryogenic treatment.

As a crucial node where long-distance pipelines enter urban pipeline networks, urban gas gate stations undertake multiple functions such as purification, pressure regulation, metering, distribution, and safety protection. Among them, valves, as one of the core equipment, their performance directly affects the stability and safety of the system. This paper focuses on analyzing the application advantages of DN300 PN40 turbine-driven trunnion ball valves in the pressure regulating system.
