Abstract
A flow-regulating valve is located in the outlet of the housing of a centrifugal pump instead of in downstream piping, to regulate the flow from the pump without the usual acoustic disturbance caused by flow. The arrangement is especially adapted for hydro-therapeutic installations, such as a spa, hot tub, whirlpool bath or the like. The valve is operated by a control conveniently accessible to the occupant of the hydro-therapeutic installation. The control can be in the form of a knob connected to the valve by flexible cable or the like or in the form of a single push-button which controls both the electric motor for the pump and an electric motor which operates the valve.
