On/off valves operate as their name implies - they turn water on and off and control volume of water. Consider this example of a typical installation - a fixed showerhead with three body/side sprays. You get into the shower with all sprays on to get wet, then (using the on/off valve) shut off the body/side sprays to lather up.
