Valves are devices that control the flow of fluids (liquids, gases, slurries) by opening, closing, or partially obstructing passageways. Industrial valves are used in a wide variety of applications in many different industries such as oil and gas, power generation, food and beverage, pharmaceuticals, chemicals, pulp and paper.
Types of Valves
There are many types of valves used in industrial and commercial applications. Valves are used to control the flow of liquids, gases, and slurries (liquid-solid mixtures).
The three main types of valves are:Ball valves: These have a spherical ball that controls the flow through the valve.
The ball is moved by a handle to open or close the valve. Ball valves are used for on/off applications and can be used with fluids that contain solids.
Butterfly valves: These have a disk that rotates to open or close the valve. Butterfly valves are used for on/off applications and can be used with fluids that contain solids. They are often used in larger diameter piping systems.
Gate valves: These have a gate that moves up or down to open or close the valve. Gate valves are used for on/off applications but should not be used with fluids that contain solids.
How to choose a valve？
There are many factors to consider when choosing a valve, such as the application, environment, and operating conditions. The most important factor, however, is the type of fluid you'll be handling.
The three most common types of valves are ball valves, butterfly valves, and check valves. Each has its own advantages and disadvantages that you'll need to consider before making a decision.
Ball valves are the most common type of valve used in industrial applications. They are durable and can handle high pressures and temperatures. However, they are not suitable for all applications because they can be difficult to operate and require more space than other types of valves.
Butterfly valves are lighter and take up less space than ball valves. They are also easier to operate. However, they are not as durable as ball valves and can only handle lower pressures and temperatures.
Check valves are used to prevent backflow in a piping system. They are typically installed in horizontal or vertical positions. Check valves come in many different sizes and designs, so it's important to select the right one for your application.
What to pay attention to when installing the valve？
When installing the valve, you need to pay attention to the following points:
1. Check if the specification and model of the valve match the drawing and piping.
2. Check whether the nameplate data of the valve (pressure, medium, caliber, etc.) is consistent with the process conditions of the pipeline.
3. Check whether there is any damage to the surface of the valve body and whether there are foreign bodies in it. If so, it should be cleaned up in time.
4. Whether all parts of the installed valve are complete, and whether they meet relevant standards.
