Abstract: The dynamic behaviors of a pilot control valve have been studied using the pseudo bond graph approach. The pseudo bond graph model can synchronously retain the mathematical structure and the ...

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.

An oscillating control valve may appear to be the source of control instability and repair efforts are usually focused only there. When this fails to solve the issue, further investigation often ...
