Many high-pressure pumps utilize pressure regulating valves, also known as by-pass valves, to divert a portion of the flow to a low-pressure outlet. Acting like a hand-adjustable needle valve, the pressure regulating valves can be used to control pressure when the application requires less flow at the work site.
