WebAug 5, 2024 · R. Russell Rhinehart. The valve characteristic represents how the flow rate through a valve changes with valve position. Desirably, for normal use, we want the characteristic to be linear (Figure 1), a constant gain, so that controller tuning at one flow rate is acceptable for all flow rates. The idealized valve equation is: WebApr 11, 2024 · The test result shows that the valve designed by simulation conforms to the specified flow characteristics. By monitoring the lift coefficient of the vortex cross flow, the amplitude and main frequency of vortex-induced vibration are evaluated. The effect of the valve plug shapes on the vortex-induced vibration characteristics is studied.
