Proper filtration is essential to process flow operation. Improper filtration or lack of filtration can wreak havoc on components, reducing their life and changing the final product. If left unaddressed, this can lead to equipment failure, process upsets, increased quality issues and in some cases, unplanned shutdown. Thus, making an investment in the correct filter for the process is a wise choice.

When control valve professionals talk about "control valve sizing," they really mean the entire process of selecting the valve that will do the best job of controlling the process. Selecting the right size valve is an important part of the process, but there are other equally important considerations as well.
