In the 1980's Moen changed their Standard Valve to a Pressure Balancing Valve called Moentrol. While the Moentrol takes the same cartridge (1225) as the Standard Valve, the screw positions on the Moentrol trim is different.
The Standard & Moentrol valves are turned on and off by pulling the handle out and pushing it back in - giving you the ability to control the volume of the water flow.
