A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll. Read More

At their most basic, valves are devices that work to control, regulate or direct flow within a system or process. They often feature a range of characteristics that help to define their ideal application. However, whether you’re looking to control flow, provide safety in a system that is piping liquids, solids, gasses or anything in between, there are likely stainless steel valves available to help.

There are two broad families of butterfly valves. Briefly, the difference is whether the stem is concentric with the centerline of the valve body or eccentric or slightly off-centre in two or three planes. This geometric difference is responsible for the differences in the way that various butterfly valves seat and shut off. These two groups overlap somewhat in rating and performance, but in the operational characteristics that really matter, such as pressure rating and shut-off ability, these two types of valve are quite different. Needless to say, because the two valves look quite alike (that is, they both are often very short face-to-face and often do not have separate flanges of their own, and they both have a disc that turns inside the pipe) and they share the butterfly valve name, they are often confused.

Valves are an essential part of any piping system, which means they play a key role in the oil and gas industry. They can be used to control flow, isolate and protect equipment, and guide and direct the refining process of crude oil. Read More

Wastewater treatment is one of the industrial processes to improve the quality of wastewater from wastewater treatment plants. The quality of wastewater treatment technology depends on the suitability and quality of the valves installed, because the sedimentation, flow control and treatment of conce Read More

Water cutting, also known as water knife, English name is high pressure water cutting, that is, high-pressure water jet cutting technology. It is a machine that uses high-pressure water flow to cut. Under the control of the computer, the workpiece can be carved arbitrarily, and it is less affected b Read More
