Problem to be solved: to provide a flow control valve capable of precisely controlling the flow rate in the small flow rate range and also controlling the flow rate in the large flow rate range. A flow control valveInlet port 3 and outflow port 4 are provided.A body 2 provided with a ...
WhenValve parameterizationisNominal capacity, superheat, and operating conditions, the block calculates the data in all quadrants by using the analytical valve model, described inAnalytical Parameterization. Because the analytical model assumes a straight-charged bulb, the diagram plots the two curves in...
Figure 34 shows the change in the cross-section area of the actual flow when it goes through a control valve. In a control valve, the flow is forced through the control valve orifice, or a series of orifices, by the pressure difference across the valve. The actual flow area is smallest ...
