Globe valves are one of the most commonly used control valves in industrial piping systems, primarily designed to stop or regulate fluid flow. In industries such as chemical, petroleum, power generation, and pharmaceuticals, the reliability of a globe valve directly affects production safety and equipment lifespan. However, with the wide variety of globe valves available on the market, how can one...

Globe valves operating under low-temperature conditions, such as liquefied natural gas (LNG), liquid oxygen, liquid nitrogen, or liquid argon, face higher demands on materials, structure, and sealing performance. In low-temperature environments, metals can become brittle, sealing materials may contract, and the valve stem area can even experience freezing blockage. Therefore, standard globe valves...

In industries such as chemical processing, pharmaceuticals, electroplating, and metallurgy, valves are often exposed to highly corrosive media such as strong acids and alkalis. Conventional metal valve bodies can hardly withstand these conditions for long periods. To extend service life and ensure safe system operation, the PTFE Lined Globe Valve has become the preferred solution for many users. W...

Globe valves are compact, reliable-sealing valves widely used in steam, oil, water, and chemical pipelines. During long-term operation or frequent cycling, internal components can experience wear, corrosion, or deformation, with valve stem bending being one of the more common issues. This article provides a professional overview of the main failure points in globe valves, the causes of valve stem ...

Globe valves are widely used across various industrial systems to control the start, stop, and regulation of fluid flow. However, in real-world operation, many users face a common question: how to accurately determine whether a globe valve is currently open or closed? This article will explain in detail how to identify the open or closed status of a globe valve based on its structural design, hand...
