Specifying control valves and engineering a system in which the flow of a particular product is completely optimized for superior performance and yield can be a challenging process. A number of factors must be considered during this practice, not the least of which is trying to prevent any system or process-destroying problems that may arise.

The ABCs of VFDs

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.

Pipe and Valve Selection

When selecting the pipes and valves to be included in a cooling system, it is important to understand the options available — and the possible outcomes associated with each selection. The selection process is often overlooked or is not given proper attention by designers and contractors. Many factors can impact the effectiveness, longevity and quality of the overall cooling system.

The Internet of Things (IoT) is a phrase that describes the connectivity between physical objects networked together using an Internet connection. These networks have a wide range of capabilities, mostly centered on collecting or exchanging data. A specialized version of the IoT, referred to as the Industrial Internet of Things (IIoT), enables industrial application engineers to implement new or retrofitted systems with upgraded levels of connectivity that allow more advanced process control.

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.

Rule of Thumb for Control Valve Sizing

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.
