Basically, valves are a type of mechanical device that can be used to control the pressure and flow of liquid in an air or hydraulic system. This is the reason they are essential parts of piping system that are responsible for the transportation of sludge, vapors, gases and liquids. You can choose from different types of valves, and each of them offers comes with a different set of characteristics, uses and capacity. Operating methods of these units are also different. They can be electric, pneumatic, or manual. Let’s find out how you can choose one.

How to choose a valve?

Before you go for a valve, make sure you consider the intended purpose. Apart from this, you may want to consider the type of media that the unit will be used to transport. It can be either liquid or gas.

Before selecting your valve, you will need to determine what it will be used for. Will it be used to regulate fluid or stop its flow?

As far as the operating system is concerned, find out if the unit is powered automatically or manually. No matter what type it is, one person should always be there to operate the unit. However, in some cases, the system can be operated remotely.

Lastly, you may want to find out the way the unit will be integrated into the piping system, especially if you need to validate it. As soon as you have decided on these factors, you may consider the technical features of the installation, such as the pressure and flow of the liquid or gas.

How to Figure out the dimensions of the valve?

For calculating the volume dimensions, you need to consider the parameters associated with the circuit operation. One of the main factors is the pressure, which is why you need to consider it to get the right size. Similarly, it’s not a good idea to get an oversized unit.

You need to consider the operating temperature of the device as well. This includes the temperature of the valve body, ambient temperature, and the circulating media temperature. It is important to find out the highest temperature the unit can tolerate without failure.

It is important to consider the operating pressure as well. Besides, the flow velocity and the flow rate of the liquid should also be considered. As a matter of fact, these two elements can help you go for the best valve to meet your needs. The flow factor is defined by the manufacturer. With the help of this factor, you can figure out the flow rate of the unit. Typically, it is given in litres per minute or cubic metre per hour.

The nominal diameter of the unit should also be considered. This can help you avoid getting the wrong size.

Long story short, if you are going to buy a valve, we suggest that you consider these important elements and factors before placing your order. Getting the right size unit is of paramount importance if you want to make your system work properly without any problems.
