A Pressure Regulating Valve (PRV), also called a By-Pass Valve, is used on both diesel and electric pumping units to divert a portion of the flow to a low pressure outlet.  It is really a hand-adjusted needle valve, and it can be used to control pressure when the application requires a flow at the low end of the pumping unit operating range.  For electric units a PRV is required because the speed of the drive is not adjustable.
