This paper concerns the development of a mathematical model for use both in predicting system behaviour and in control valve design. The first model considered includes several parameters whose values may only be found by experimentation, whilst the second model may be synthesised using only readily available data. The response of each of the simulation models is compared to experimentally obtained results obtained from a 2 in regulator and the effects of parametric variations are considered. It is shown that the transient response of this type of valve may be modelled by the use of the reasonably simple simulation model described.
