Understanding Trunnion-Mounted Ball ValvesDesign and FunctionTrunnion-mounted ball valves are designed to handle high pressures and large flow rates, making them suitable for critical industrial applications. The key design feature is the trunnion or ear-axis mechanism, which supports the ball and r

In the field of transportation and control of cryogenic media such as liquefied natural gas (LNG), liquid oxygen, and liquid nitrogen, ultra-low temperature trunnion ball valves have broad application prospects. Under cryogenic working conditions, such valves not only need to have reliable sealing p

Pneumatic ball valves are widely used in various industrial applications due to their reliability, ease of operation, and ability to provide precise flow control. With the advancement of technology, the integration of intelligent control and remote monitoring systems has become increasingly importan

What is a Trunnion Mounted Ball Valve?A trunnion mounted ball valve adopts an upper and lower support bearing design, which keeps the ball stable in high-pressure environments and prevents displacement caused by medium pressure. Its core advantages include:Low operating torqueReliable high-pressure

Super-large diameter welded ball valves are crucial components in various industrial applications, including oil and gas pipelines, petrochemical plants, and power generation facilities. These valves are designed to provide reliable flow control and tight sealing under extreme pressure and temperatu

Understanding Floating Flanged Ball ValvesFloating flanged ball valves are a type of ball valve that uses a floating ball mechanism to achieve fluid control. The ball is supported by the upstream pressure, allowing it to move slightly and maintain a tight seal against the valve seat. This design ens

In industrial pipeline systems, "leakage", "jamming", and "short service life" are almost unavoidable pain points for every purchaser, engineer, and maintenance personnel. Especially under working conditions of high pressure, high corrosion, or continuous operation, even a 1% failure of a floating ball valve assembly may cause the entire production system to shut down. But the question is—why do ball valves that seem identical on the market have such huge differences in actual performance?

1. Overview of DBB Ball ValvesA Double Block and Bleed (DBB) ball valve is a high-performance valve that integrates dual sealing and bleeding functions. Its design concept relies on two independent sealing surfaces to achieve dual isolation of pipelines, with a bleed port installed in the valve cavi

In the field of industrial fluid transportation and control, the reliability, sealing performance, and operational convenience of valves are directly related to the efficiency and safety of the entire system.

In the field of industrial valves, J-VALVES has created valve solutions with exceptional performance and reliability through extreme innovation in the seat and stem systems. These solutions provide solid guarantees for the harsh working conditions in industries such as oil and gas, chemicals, and en
