Function

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 bypass the differential pressure created by the pump

as the zone valves close, thus eliminating water hammer noise.
