A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

Figure 1. High-pressure district or campus steam is reduced to lower pressure for building use. The controller receives the low-pressure steam reading from the transmitter and regulates low-flow ...

Valves are essential elements for controlling fluid system performance. Virtually every fluid-power system requires some type of valve. In a hydraulic system, valves may control pressure, flow to an ...

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 ...

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.

ISA recently published Fluid Mechanics of Control Valves: How Valves Control Your Process by Hans D. Baumann, Ph.D., PE — a world-renowned expert on control valve technology who is credited with more ...
