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

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

As a key equipment widely used in industries such as petroleum, natural gas, and chemical engineering, the trunnion ball valve's cost control is of crucial importance for enterprises. Reducing the cost of trunnion ball valves can not only improve an enterprise's market competitiveness but also bring

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 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

International Standards for Ball Valves(1) ISO StandardsThe International Organization for Standardization (ISO) has developed a series of standards for ball valves, among which ISC17292 is one of the most important. This standard specifies the design, manufacturing, and acceptance requirements for

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 shaft ball valve is widely used in multiple fields such as petroleum, chemical engineering, natural gas and water treatment

Structural characteristics of trunnion ball valves. (I) Trunnion support design. The core structure of a trunnion ball valve is the trunnion support system. The ball is fixed by trunnions at the top and bottom. This design significantly reduces the friction between the ball and the valve seat, and a

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

Trunnion ball valve is a high-performance industrial valve. Due to its unique design and excellent performance, it has been widely used in the oil and gas industry. It supports the ball through a trunnion, reducing friction and enhancing sealing performance. It is especially suitable for high-pressu

In modern industry, skid-mounted systems, as an integrated and highly efficient equipment unit, are widely used in multiple fields such as petroleum, natural gas, and chemical industry. Trunnion ball valves, as a high-performance valve type, due to their unique design and excellent performance, have

In industrial fluid control systems,ball valves are widely used due to their advantages such as compact structure, good sealing performance, and simple operation. Among them, floating ball valves and trunnion ball valves are two common types. They have their own characteristics in structure, perform
