I just came across this yesterday when I stopped in to see an old friend who had recently moved in down the road. He had a new well drilled and the pump control installation included one of these valves. It is a special pressure regulating valve that goes between the pump and the pressure switch to throttle the pump output, instead of controlling the pressure by starting and stopping the pump. The pump will still have to be controlled by the pressure switch but for as long as water is being continuously drawn the pump will continue to run. Any pump which is moving less water will draw less current, but the main thing is that the pump doesn't start as often saving the motor, and that you maintain constant even pressure for your water uses. I will be putting one in soon. Don't condemn it without becoming informed if you don't know about it.
