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

I. Unique Advantages of J-VALVES SCS13 Floating Ball Valve(A) Structure and Sealing PerformanceThe J-VALVES SCS13 floating ball valve adopts an advanced floating ball structure. Under the action of the medium pressure, the ball can automatically apply pressure to the downstream sealing surface, thus

In the field of industrial valves, TRUNNION BALL VALVES have drawn much attention due to their unique design and wide range of applications. This article will conduct a detailed analysis of the comprehensive advantages of J-VALVES TRUNNION BALL VALVES in terms of DN specifications and pressure ratings by comparing design standards.
 

In the global industrial field, DN300 PN40 trunnion mounted ball valves are widely used. API 608 and EN 12516, as important international standards, have different specification requirements for their design, manufacturing, performance and other aspects. Understanding the compatibility between these two standards is of great significance for relevant enterprises in international trade, product selection and project implementation. Now, let's conduct an in-depth analysis of the comparison of these two standards in various key elements.

I. DESIGN FEATURES OF TRUNNION FLANGE BALL VALVES The design of TRUNNION FLANGE BALL VALVES is an important guarantee for their performance and reliability.According to the information I've searched, TRUNNION BALL VALVES​ usually adopt a three-piece or two-piece structure. Their characteristic is that the ball is fixed on the valve seat and will not shift when the valve is closed, thus ensuring stable and reliable sealing performance. In addition, they have a low operating torque and uniform sealing, making them suitable for high-pressure and large-diameter working conditions. For example, the Q476F type three-piece soft-seal flange ball valve of the J-VALVES brand is designed in accordance with API standards and has excellent sealing and pressure resistance.

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 industrial fields such as petrochemical and natural gas transportation, the complex working conditions of high temperature and high pressure pose stringent requirements for the performance of valves. Thanks to its unique structural design and excellent performance, the trunnion ball valve has bec

Ball valves, as an important type of industrial valve, are widely used in fields such as petroleum, natural gas, chemical engineering, and power. With the continuous development of industrial technology, the performance requirements for ball valves are getting higher and higher, especially under ext

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.


I. Requirements for Valves in LNG Low-te

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 the petrochemical industry, the safety and reliability of valves are one of the key factors in ensuring production safety. Fireproof certification (such as API 607) is crucial for ensuring the performance of valves under fire conditions. Meanwhile, with the development of technology, alternative solutions to butterfly valves are constantly emerging. This article will compare the fireproof certification (API 607) of trunnion ball valves and gate valves and explore alternative solutions to butterfly valves to help practitioners in the petrochemical industry make wiser choices.
