This page helps engineers, buyers, and project teams compare API 6D vs API 608 for trunnion ball valves, with a clear focus on scope, application, end connections, pressure classes, and practical selection guidance for pipeline, refining, and industrial projects.

Learn how ISO 5208 relates to trunnion ball valves, pressure testing, sealing performance, and industrial valve acceptance. Ideal for oil & gas, chemical, power, and pipeline projects.

In various industrial and civil pipeline systems, ball valves can be seen everywhere. With many advantages such as simple operation and excellent sealing performance, they play a vital role in numerous fields like petroleum, chemical engineering, gas, water supply and drainage. However, there are a

In industrial application scenarios with high temperature and high pressure, the selection of valves is of crucial importance. As two common types of valves, trunnion ball valves and gate valves have significant differences in their pressure ratings under the ASME B16.34 standard.

In the field of industrial valves, zero leakage technology has always been the goal pursued, especially when dealing with hazardous media or working conditions with high requirements. Metal sealing of trunnion ball valves and soft sealing of gate valves are two common sealing methods, and there are

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 fluid control process in the industrial field, J-VALVES DN300 PN40 trunnion ball valves are widely used due to their unique structural and performance advantages. However, different design standards result in differences in many aspects of trunnion ball valves of this specification. A clear understanding of these differences is crucial for us to make accurate procurement decisions. The following is an in-depth comparison of its common design standards to clear up the confusion for you.

In the current complex industrial and living scenarios, valves play a vital role in fluid control. J-VALVES stainless steel trunnion ball valves stand out among numerous industries by virtue of their unique product features and wide adaptability, and have won the praise of being "all-round valves".

Understanding Ear-Axis Ball ValvesKey Features of Ear-Axis Ball ValvesEar-Axis Design: The ear-axis design allows for the valve to be mounted on a vertical axis, providing stability and reducing the risk of misalignment. This design is particularly beneficial in high-pressure and high-temperature ap

As a high-performance industrial valve, trunnion ball valves are widely used in high-pressure and high-temperature working conditions in industries such as petroleum, natural gas, and chemical engineering. However, due to the complexity of its working environment, the stability of trunnion ball valv

Structural Design of Trunnion Ball Valve(1) Trunnion Support StructureDesign Principle· The core design of the trunnion ball valve is to fix the ball in the valve body through the trunnion, and the ball will not move towards the valve seat during the operation. This design significantly reduces the

Stainless steel trunnion ball valve is a high-performance ball valve. Its core component is a sphere with a through hole. The sphere is fixed in the valve body through trunnions and can rotate 90 degrees. This design not only ensures the compactness and stability of the valve, but also improves the

I. Key Factors of Sealing Performance(I) Sealing MaterialsThe sealing performance of trunnion ball valveslargely depends on the selection of sealing materials. Common sealing materials include polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), and metal seals. These materials not only have

In the global valve manufacturing field, J-VALVES from China is standing out with its outstanding manufacturing capabilities and innovative technologies. Recently, the ball valves launched by J-VALVES, which comply with the GOST Russian standard and adopt the Trunnion Ball Valves DIB-1 seat design,

I. Structural Features of Trunnion Ball ValveThe core component of the trunnion ball valve is the ball, which is fixed to the valve body through trunnions. This structural design makes the ball more stable during rotation, reducing the risk of displacement caused by vibration or impact. Compared wit
