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 are indispensable components in fluid control systems. There are numerous types of valves, including DBB flanged floating ball valves, gate valves, plug valves, etc. Each type of valve has its unique structure, performance, and applicable scenarios. This article will

In today's rapidly developing industrial era, valves, as indispensable and crucial components in industrial systems, are playing an increasingly significant role. They are not only related to the smoothness and safety of the production process but also a key link for enterprises to achieve efficient

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

I. Unique Advantages of J-VALVES SCS13 Floating Ball Valves(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, thu

Three-piece vs Two-piece Ball Valves: In-depth Evaluation of Structural Strength and Maintenance CostsIn industrial fluid control systems, ball valves, as an important control element, are widely used in various pipeline systems. Three-piece ball valves and two-piece ball valves are two common types

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 high-risk industries such as petroleum, natural gas, and chemical engineering, the fire resistance of valves is of crucial importance. As a widely used type of valve, the fire safety certification of J-VALVES ball valves is a key aspect in ensuring the safety of equipment and personnel. This arti

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 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 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.

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.
