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 ...

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 ...

This paper systematically elaborates on the turbulence model, multiphase-flow model, and noise model. The turbulence model is adept at accurately characterizing the flow behavior of complex fluids. In ...

The paper proposes the full linearization of nonlinear characteristics of flow control valves via variable gear ratio design. The inherent nonlinear function of the normalized valve capacity ...
