The differential pressure by-pass valve is used in systems with a fixed speed circulating pump supplying several zones controlled by two-way zone valves. This valve ensures that the head pressure of the pump is proportional to the number of two-way valves being closed. It will by-pass the differential pressure created by the pump as the zone valves close, thus eliminating water hammer noise.
