In hydraulic systems, lubrication systems, and even automotive engines, "clean oil" is the cornerstone of reliable operation. To filter out contaminants from oil, two common devices are used: oil filters and strainers. While often grouped under the umbrella term "filters" in Chinese, they serve distinct roles in engineering applications. This article dissects their differences across multiple dime...

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...

Both V-port ball valves and O-port ball valves are important types of ball valves, with clear differences in design, applicable media, and control performance. Understanding these differences helps engineers make more appropriate selections for specific applications. Design and Characteristics of V-Port Ball Valves V-port ball valves feature a distinctive partial-sphere ball design w...

1. What Is a Valve Welding Electrode? A valve welding electrode refers to a category of welding consumables specifically used for hardfacing, repair welding, and overlay welding of valve components, including the valve body, sealing surfaces (such as valve seats and valve discs), as well as welding joints between valves and pipelines. It is not a single product, but rather a general ...
