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.

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

J-VALVES always takes technological innovation as the core driving force for enterprise development, continuously increases investment in research and development, introduces advanced technologies and equipment, and cultivates a high-quality R & D team.

In the oil and gas industry, valves, as key fluid control equipment, have a direct relationship between their performance and reliability and the safety and efficiency of the entire production system. As a high-performance valve type, high-pressure large-diameter trunnion ball valves, with their uni

As a high-performance industrial valve, trunnion ball valves are widely used in high-pressure and high-temperature working conditions in industries such as petroleum, natural gas, and chemical engineering. However, due to the complexity of its working environment, the stability of trunnion ball valv

The main structure of a ball valve includes a valve body, a ball, a valve seat, a valve stem and an actuator. The valve body is the shell of the ball valve and is usually made of metal materials to withstand fluid pressure and support internal components. The ball is the core component of the ball v

In the application of Trunnion ball valve, the DBB (Double Block and Bleed) seat design is a common choice. Its unique structure gives it significant advantages under specific working conditions. The following are the appropriate times to choose the DBB seat design and related considerations.Applica

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 ball valve: The ideal choice for industrial fluid control.Excellent corrosion resistance. Stainless steel ball valves are made of high-quality stainless steel materials and have excellent corrosion resistance. They can operate stably for a long time in harsh environments such as acid

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
