Inside of plants today, AC motors are becoming the industry standard. Many plants are shifting to AC motors from hydraulic motors and in some cases DC motors when powering heavy loads, which were more popular in the past. This shift can be attributed to a variety of reasons and most have to do with cost.

Just as sound can have negative effects on the human body, certain frequencies can play havoc on industrial equipment. When control valves are not selected appropriately, there is an increased risk for cavitation, which causes high noise and vibration levels, resulting in very rapid damage to the valve's internals and/or the downstream piping.

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.
