A pressure relief valve (or automatic by-pass valve) is connected between the feed and return pipes, this allows the pump to circulated the water from the boiler if all the radiators should be shut off. Because of the restriction of flow imposed by the radiators, the number of radiators is limited basically by the size of circulating pump.

Under normal working conditions, the pump delivery pressure is higher than the boiler pressure. So the valve is lifted from its seat and allows the water to flow to the boiler. The lift of the valve is controlled by moving the spindle up and down with the help of the handwheel. Thus, the flow of water can be controlled. Diagram of Feed Check
