Overview of the Standards1. API 6D: Pipeline and Pipeline ValvesAPI 6D is a standard developed by the American Petroleum Institute (API) specifically for pipeline valves used in petroleum and natural gas systems. It focuses on gate, ball, check, and plug valves and is designed to address the unique

I. Core Application Scenarios of 24-inch 300LB Cast Steel Flange Gate Valves(1) Main Feedwater/Steam Systems in Thermal Power PlantsThe main feedwater and steam systems in thermal power plants have extremely high requirements for the pressure resistance, high temperature resistance, and sealing perf

In the industrial field, valves, as key components of fluid control systems, are crucial for the efficient operation of the entire production process due to their performance and flexibility. The J-VALVES CF8 pneumatic fixed ball valve has become the preferred product in numerous industrial applicat

In the procurement of industrial valves, it is crucial to ensure the quality and performance of valves. The API 598 standard provides clear guidance for the inspection and testing of valves, helping purchasers make informed decisions when choosing TRUNNION BALL VALVES, GATE VALVES and BUTTERFLY VALVES. This article will compare in detail the API 598 testing costs and acceptance procedures of these three types of valves to help you better understand and choose suitable valve products.
 

In industries such as petroleum, natural gas, and chemical engineering, the API 6D standard is an important basis for the design, manufacturing, and testing of pipeline valves. This standard covers multiple types of valves, including trunnion ball valves, gate valves, and butterfly valves, etc., and is widely used in long-distance transmission pipelines, oil and gas field development, and industrial pipeline systems. This article will conduct an in-depth analysis of the design specifications for trunnion ball valves and gate valves under the API 6D standard, compare their structural characteristics, performance requirements, and application scenarios, and also explore the applicable scenarios of butterfly valves.

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 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 industrial pipeline systems, ball valves are widely used due to their simple structure and convenient operation. However, in high-temperature and high-pressure working conditions, the choice of sealing materials directly affects the reliability and service life of the valves. This paper will mainly discuss the performance differences between PTFE and metal-to-metal hard seal materials and their applicability in 450°C steam pipelines.

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.
