Some small-capacity water-cooled refrigeration systems use municipal water as their cooling medium. These systems will typically add a regulator to control water flow through the condenser. These ...

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 ...

A solenoid valve is an industrial device controlled by electromagnetism which controls fluids, adjusting the direction of the medium, flow, speed and other parameters. There are many solenoid valves ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

• The first step in selecting a valve is determining its function. • Review Cv or pressure drop when considering one valve versus another. • Don’t overlook maintenance requirements when specifying a ...
