restrictions restrictions

I have recently discovered that the 1989 LTD that I have has a restricter installed in the high pressure side of the heater hose. This was blocked and did more that restrict the flow of coolant to the heater core, it brought it to a stop. Does any one know if this device must be in line to produce proper heating in the cabin or is it a device designed to save the heater core. In other words is it necessary???

The restrictor is inserted inside the heater hose with no external attachment to it. It is a cylinder approx 1/2 to 3/4 inch in length with a hole down the centre about half the diamater of the internal diamater of the hose. it looks as though at one time it contained some kind of flap valve
