Toggle navigation. C D is the value of the Discharge coefficient block parameter. The pressure-reducing valve runs between the inlet P and the outlet A. The pressure ratio is defined as the gauge pressure at the outlet divided by the same at the inlet. Opening Dynamics By default, the valve opening dynamics are ignored.

    Opening through which the flow can enter the valve. When set point is exceeded, the diaphragm is lifted off the center port, and excess flows "down" and out through the third port at the bottom of the valve. Smoothing factor for easing the transition to the fully open or fully closed valve position. The flow rates through each of the elementary valves are defined as:.

    The block uses this parameter to calculate the initial rate at which the pressure-reducing valve is opening and from it the instantaneous opening area at the next time step.

    The valves then open each at a rate given by the expression:. Parameter in terms of which to specify the boundary between the laminar and turbulent flow regimes. The block uses this parameter to calculate the initial rate at which the pressure-relief valve is opening and from it the instantaneous opening area at the next time step.

    C D is the value of the Discharge coefficient block parameter.

    Relief setting is infinitely adjustable from 5 psi to psi. If you are unsure which is right for your application, please contact our Technical Services Group at The value specified here is shared by both pressure-reducing and pressure-relief valves.

    The smoothing enhances the numerical robustness of the model, helping to avoid numerical errors due to discontinuities and simulation slowdowns due to zero crossings.

    Smoothing factor for easing the transition to the fully open or fully closed valve position. Opening through which the flow can exit the valve. Reynolds number at which the flow is assumed to transition between laminar and turbulent regimes. Measure of the time taken by the valve to transition from its current opening area to a new steady-state value.
