You might think that butterfly valves are only used for controlling water. In fact, they have long been employed in various "hellish environments". Rocket engine: In the liquid hydrogen and liquid oxygen propellant pipelines, the temperature drops as low as -253℃. Ordinary rubber and plastic would ... Read More

You may have noticed that many floor heating valves or radiator side panels have a white knob with markings (1 to 5 levels). It doesn't require power plug or battery installation, yet it can function like a smart air conditioner, adjusting the water flow size based on the room temperature. When the ... Read More

Tap water flows steadily and cleanly from reservoirs or major rivers and streams dozens of kilometers away through a complex network of underground pipes to your home’s faucet—a process that is, in fact, a precise “fluid symphony.” Water treatment plants focus on two core aspects of water management...

Why do the butterfly valves in a building’s fire protection piping systems all have cables attached? The reason butterfly valves on a building’s fire protection piping are connected to cables is simple: they serve as the “eyes” of the fire protection system. These cable-connected valves are ...

A standard butterfly valve is a “center-mounted butterfly valve,” in which the valve stem passes through the center of the disc. With this design, the disc and rubber seat are in constant contact during opening and closing, leading to wear and tear, and the valve is prone to leakage under high ... Read More

The butterfly valve not only transports clean water, but also quietly withstands pressure in many "high-tech" scenarios that you might not expect: At a temperature of -196℃ (LNG liquefied natural gas): When natural gas is frozen into liquid for transportation, the temperature is so low that it can ...

Although the name "Butterfly Valve" sounds like a beautiful insect, it is actually a vital fluid control champion in both industry and everyday life. Whether in water mains, HVAC systems, or massive chemical plants, you can find it everywhere. Here is a breakdown of some cool and interesting facts ... Read More

Choosing between a butterfly valve and a gate valve is one of the most common decisions in piping design. While both are excellent for isolating fluid flow, they operate on completely different mechanical principles and excel in different environments. Here is a breakdown of how they compare, how ...

All products have been inspected and qualified in accordance with the relevant standards before leaving the factory, and the actuator has been debugged. To ensure the use effect of the product, do not arbitrarily adjust fasteners, positioning devices, etc. Pre-installation Work • Ensure that the ... Read More

I. Impact on Sealing Performance 1. Grade VI The medium hardly leaks from the sealing surface. The storage and pressure retention effect is excellent when the pipeline is fully closed; it is suitable for applications requiring strict isolation: tap water, pure water, pharmaceutical solutions, gas. ...
