How to choose the right valve ?

Are you struggling to choose the right valve for your project? Are you troubled by the wide variety of valve models and brands on the market? In all kinds of engineering projects, choosing the right valve is very important. But the market is full of valves. So we have put together a guide to help you easily and wisely choose the right valve product for you. Whether you need flow control, pressure regulation or fluid cutoff, we’ve got some tips and tricks for you. Take a confident step through this valve maze and enjoy cost and time savings while working on an efficient engineering project.

1.Identify the purpose of the valve in the equipment or device 

  Determine the working conditions of the valve: the nature of the applicable medium, working pressure, working temperature and control mode.

2.Select the correct valve type 

  The correct choice of valve type is based on the designer’s full grasp of the entire production process and operating conditions as a prerequisite, in the selection of valve type, the designer should first master the structural characteristics and performance of each valve.

3.Determine the end connection of the valve

  In threaded connections, flange connections, and welded end connections, the first two are most commonly used. Threaded valves are mainly valves with nominal diameter below 50mm, if the diameter size is too large, the installation and sealing of the connection part is very difficult. Flange connected valve, its installation and disassembly are more convenient, but the more threaded connected valve is bulky, the price is higher, so it is suitable for a variety of diameter and pressure of the pipeline connection. The welded connection is suitable for higher load cutting conditions and is more reliable than the flange connection. However, the disassembly and reinstallation of welded valves are more difficult, so its use is limited to occasions where it can usually operate reliably for a long time, or where the conditions of use are engravings and the temperature is higher.

 

4.Valve material selection

  The selection of valve shell, inner parts and sealing surface material, in addition to considering the physical properties of the working medium (temperature, pressure) and chemical properties (corrosion), should also master the cleanliness of the medium (there are no solid particles), in addition, but also refer to the relevant provisions of the state and the use of the department. The correct and reasonable selection of valve material can obtain the most economical service life and the best performance of the valve. The selection sequence of valve body materials is: cast iron – carbon steel – stainless steel, and the selection sequence of sealing ring materials is: rubber – copper – alloy steel -F4.

  In addition, the flow rate and pressure level of the fluid flowing through the valve should be determined, and the appropriate valve should be selected using the available information (such as the valve product catalog, valve product samples, etc.).
