On any type of refrigeration system, from small reach-in coolers all the way to large chillers, controlling the head pressure of the refrigerant is important. That’s because it helps keep the system ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

When troubleshooting a refrigeration system, it is important to understand how the refrigeration cycle accomplishes the goal of removing heat from a room and rejecting the heat absorbed by the ...

The Aventics Series 625 Sentronic proportional pressure control valves feature a control deviation of less than 0.5% to deliver accurate, electronic proportional pressure control and provide the ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

Pressure relief valves (PRVs) are a critical line of defense for pressure vessel protection in the power industry. Generating facilities worldwide depend upon these devices to sense and quickly ...

Off-highway construction machinery can exponentially benefit from a simple system upgrade to improve efficiency and overall ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...
