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
