A pulsing valve for routing water flow from an inlet line to outlet lines connected to water jets arranged in an array to massage an occupant of a whirlpool spa or bathtub is provided. The pulsing valve includes a water turbine driving a selector disk through a reduction gear drive. The selector disk contains openings which oppose individual outlet water lines and direct water flow to them. Rotation of the selector disk switches or cycles pressurized water flow among the individual outlet water lines, causing the massaging water jet location to move, improving the quality of the resulting massage. The speed of the cycling of the water can be changed by changing the pressure of the water delivered to the water turbine. Additionally, the water turbine can be powered by tap water instead of pressurized water and the valve can be used to cycle tap water to the individual jets instead of cycling pressurized water. The pulsing valve can be used to cycle air to the individual jets instead of cycling pressurized water. Finally, a selector on the valve is used to control the flow of water through the valve outlets, the selector initiating flow of water through the outlets at a different rate than the selector terminates the flow of water through the outlets.
