Series 519 Submittal

Application
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.
