What is Valve Authority?
Equilibar control valves respond to miniscule pressure changes in milliseconds and have near zero hysteresis or deadband. PID loop can easily control close to zero valve dP.

Control the Flow of a Pump
A benefit of using a back pressure regulator to control the flow of a pump is that it is easily manufactured from materials compatible with process fluids.
-
Flow Control: Controlling Pump Slip in Positive Displacement Pumps
Maintain stable output flow rate downstream of positive displacement pumps such as gear pumps, lobe pumps and diaphragm pumps.
-
Pump Pressure Sustaining Valves
A properly sized pressure sustaining valve can create just the necessary amount of resistance to accurately control pump discharge pressure.
-
Pressure Bypass Valves and Pressure Bypass Regulators
Pressure bypass valves control pressure by diverting a portion of the flow, typically bypassing fluid from the outlet of a pump.
