Gate valves are among the most commonly used shut-off valves in industrial piping systems. With their simple structure, low flow resistance, and reliable sealing performance, they are widely applied in the energy, petrochemical, water treatment, and metallurgical industries. However, a gate valve is not a “universal solution.” Using the wrong medium, incorrect installation, or operatin...

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 industrial piping systems, high-temperature and high-pressure conditions have always placed stringent demands on valves. Traditionally, gate valves and ball valves have been the mainstay in such environments, offering reliable sealing performance and pressure-bearing capacity. With advances in valve materials and structural design, however, an increasing number of companies are now asking: &nbs...

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 ...

In modern industrial and commercial projects, valve selection directly affects system efficiency and maintenance costs. Butterfly valves, with their simple design, reliable sealing, and lightweight construction, have become one of the most common flow control devices in HVAC systems as well as in municipal water supply, wastewater treatment, and cooling water circuits. But what makes butterfly val...

In industrial piping systems, ball valves and globe valves are two of the most commonly used control components. Both are capable of regulating and shutting off fluid flow, yet they differ significantly in structure, working principle, and application scope. If you have ever hesitated between choosing a ball valve or a globe valve while designing or maintaining a fluid system, this a...
