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...

When you turn on your tap or run a washing machine, have you ever wondered what device quietly controls the water flow?Chances are, it's a small but essential component - the ball valve. A ball valve controls flow by rotating a handle 90 degrees to open or close a hole through the center of a spherical disc. When aligned with the pipeline, the medium (water, oil, or gas) flows freely; when ...

In industrial settings, quickly and accurately determining whether a ball valve is open or closed is a fundamental yet critical skill. Misjudgment can lead to production stoppages, fluid leaks, or even safety incidents. Fortunately, the design of ball valves provides several intuitive indicators. 1. The Most Direct Method: Observing the Handle Position For the most commonly used hand...

In industrial piping systems, the gate valve is one of the most widely used valves. Its key advantage lies in providing either a fully open flow path or a complete shutdown, ensuring excellent sealing performance with minimal pressure drop. Because of this, gate valves are regarded as the “gatekeepers” of safe system operation in critical industries such as power generation, petrochemi...

Have you ever considered whether a butterfly valve is suitable for your piping system design? Or have you experienced leakage or operational difficulties when using a butterfly valve under high pressure, high temperature, or viscous media? Butterfly valves are widely used in water, gas, steam, and low-pressure piping systems due to their simple structure, lightweight design, quick operation...

1.Introduction In the transportation and storage of cryogenic media such as liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, and liquid hydrogen, the reliability and maintainability of valves are of critical importance. Cryogenic butterfly valves are not only capable of operating reliably under extreme low temperatures, but are also designed with “easy maintenance” i...
