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...

Introduction In industrial fluid control systems, gate valves, as a type of shut-off valve, have long played a key role in opening and closing operations. With increasingly complex operating conditions, higher demands are being placed on valves in terms of corrosion resistance, wear resistance, and service life. Among the many available materials, duplex stainless steel (ASTM A995 5A) combi...

In industrial pipeline systems, the gate valve is one of the most widely used types of shutdown valves. It is favored for its simple structure, reliable sealing, and low fluid resistance, making it a key flow control device in industries such as oil and gas, chemicals, power generation, metallurgy, and water treatment. So, in what situations is a gate valve most suitable? This article provides a d...

Ball Valve Overview The ball valve evolved from the plug valve. Its closing element is a spherical ball that rotates 90° around the valve stem axis to open or close the valve. Unlike plug valves, the ball valve’s plug is spherical with a circular bore or passage running through its axis. When the ball rotates 90°, the inlet and outlet are completely blocked by the solid ball s...
