Ken The mechanism for pressure balancing is directly connected to the handle. In summary , when the cold pressure drops ( say , due to flushing a toilet or turning on the tap at the sink ) the shower valve is arranged, to reduce the hot water flow (because it is now the higher pressure ) and keep the water temperature out of the shower head , roughly the same. you must remember when you were young , that when someone flushed a toilet , you would get scalded at the shower. The pressure balancing shower valves solve that problem. However , when you shut the flow off, after the pressure reducing valve, and someone uses the hot water , the balancer favors to the cold side , giving you hot water at the shower valve when it is again turned on. Vice versa would apply , if someone turns on the cold water . It is a reverse acting valve.
Hope this explains it
