This is the desired control loop operation. Figure 1. Example of a temperature control loop. Controlling flow through a centrifugal pump. Referring to the pump flow control example in Figure 2, the ...

If the P 1 pressure and flow area remain fixed, flow through the valve will rise as P 2 is reduced, but at some point, choking will begin to occur and the flow will rise no higher, regardless of the ...

Plots produced by this module display values of actual motion parameters rather than target values calculated by the control loop algorithm. The plots let them chart expected activities such as ...

QPV Series valves use closed-loop pressure control. Output pressure, proportional to an electrical command signal, is unaffected by changes in supply pressure. An inlet solenoid valve shifts ...
