I. Structural Features of J-VALVES Fully Welded Ball Valves and Split-Type Ball Valves(I) Fully Welded Ball ValvesThe fully welded ball valve is a ball valve with an integral structure. Its valve body is connected into a whole through the welding process. The advantage of this structure lies in redu

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".

In the field of industrial fluid control, valves, as key equipment, have their technological development always closely linked to industry demands. With the continuous progress of industries such as petrochemical, natural gas, and electric power, the performance requirements for valves are gradually increasing. From traditional gate valves to modern fully welded trunnion ball valves, valve technology has undergone significant iterations. This article will explore this technological iteration path and analyze the future development trends of valves.

In industrial systems, check valves and ball valves are two common types of valves, and they play important roles in fluid control. However, there are significant differences between these two types of valves in terms of structure, working principle, application scenarios, as well as advantages and disadvantages. This article will conduct a comprehensive comparison between check valves and ball valves in tabular form to help readers better understand their applicable scopes and the pros and cons.

In industrial pipeline systems, the selection of valves not only affects the operating efficiency of the system but also directly relates to the overall cost of the project. The full-bore design of trunnion ball valves and the reduced-bore structure of gate valves are two common valve design methods, each with its own unique advantages and cost-benefit characteristics. This article will help you make a wiser choice when purchasing valves through detailed comparative analysis.

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.
 

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.

In steam systems, the selection of valves is crucial for the safe and efficient operation of the systems. The BS 1873 standard provides important technical guidance for the design and operation of steam systems.
