Just as there are different equipment for different types of work, there are different values for different purposes. Not all values can be used in place of the other. They have different specifications and features. Thus, it is important to carefully specify the valves which will be required for a particular type of work.
Every air valve has its own function and its function cannot be performed by the other valves. So, it is necessary to use the particular air valve for the purpose. There are certain mistakes which most of the people commit while specifying the values. These mistakes can prove to be costly. So, you should know about the common mistakes and try to avoid them.
Most of the common mistakes which happen are due to similar names. Some of the equipment is also known by different names. For example, pressure regulators are also called pressure sustaining valve. However, there is certain equipment whose name is often confused with the other equipment like the back pressure regulators which are commonly confused with pressure regulators. Their functions are slightly different from each.
The back pressure regulator provides an obstruction to flow and thus regulating the back pressure whereas the pressure valve is an open valve which regulates undesirable higher upstream pressure. Thus, if you get confused between the open pressure regulator and the back pressure regulator, then the return tank will not be able to maintain any upstream pressure which would allow the liquid to simply pass through to the return tank.
For the safe operation of the system, material compatibility is very important. You should always carefully check the material which you are using. If there is any misapplication of the material, it could be catastrophic. If the material is incompatible, it could result in the corroding of the pipe and the values, which may result in leakage and causing damage to the workers, which ultimately results in the loss of productivity.
Moreover, there will additional expenses on the cleaning of the chemical spills. However, this could be avoided if you have the required knowledge of the concentration and temperature of the fluids which are handled and also the material of the seal.
Now that you know about the common mistakes while specifying valves, you should try to learn from them and make sure that you do not commit the same mistakes.
