In modern industrial production, fluid control is a key link to ensure the smooth progress of the production process. As an efficient and reliable fluid control device, the ear trunnion ball valve is widely used in multiple fields such as petroleum, chemical engineering, natural gas and water treatm

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.

Application Practice of Low-temperature Trunnion Ball Valves in the LNG Field(1) LNG Receiving TerminalThe LNG receiving terminal is an important link in the liquefied natural gas industry chain, responsible for receiving, storing, and transshipping LNG. In the receiving terminal, low-temperature tr

Understanding Trunnion-Mounted Ball ValvesStructure and FunctionTrunnion-mounted ball valves are a type of ball valve designed with a fixed ball supported by a trunnion, which enhances stability and reduces operational torque. This design allows for precise control and reliable sealing, making them

Understanding Ear-Axis Ball ValvesKey Features of Ear-Axis Ball ValvesEar-Axis Design: The ear-axis design allows for the valve to be mounted on a vertical axis, providing stability and reducing the risk of misalignment. This design is particularly beneficial in high-pressure and high-temperature ap

Ear-Axis Ball Valves: Design StandardsKey Design Features• Ear-Axis Mechanism: Ear-axis ball valves feature a unique support structure with an axis or shaft that extends through the valve body, providing additional stability and support to the ball. This design ensures reliable operation and minimal

Structural Design of Trunnion Ball Valve(1) Trunnion Support StructureDesign Principle· The core design of the trunnion ball valve is to fix the ball in the valve body through the trunnion, and the ball will not move towards the valve seat during the operation. This design significantly reduces the

Stainless steel trunnion ball valve is a high-performance ball valve. Its core component is a sphere with a through hole. The sphere is fixed in the valve body through trunnions and can rotate 90 degrees. This design not only ensures the compactness and stability of the valve, but also improves the

I. Key Factors of Sealing Performance(I) Sealing MaterialsThe sealing performance of trunnion ball valveslargely depends on the selection of sealing materials. Common sealing materials include polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), and metal seals. These materials not only have

I. Structural Features of Trunnion Ball ValveThe core component of the trunnion ball valve is the ball, which is fixed to the valve body through trunnions. This structural design makes the ball more stable during rotation, reducing the risk of displacement caused by vibration or impact. Compared wit

In industrial production, ball valves, as the core components of fluid control systems, have their performance directly affecting the stability and safety of the systems. Especially in environments with strongly corrosive media, how to extend the service life of ball valves and improve their reliability has become a key issue. This article will mainly discuss the design of ball valves with 316L stainless steel material combined with cemented carbide sealing technology and its application in DN300 PN40 fixed ball valves.
