The differential bypass valve is used in systems where heatingloads may be excluded from the circuit as zone valves close. Itcontrols the excess flow in the system by acting as a bypass whileensuring adequate flow to the remaining open circuits. Thedifferential bypass valve helps reduce velocity noise caused byexcess flow throught the circuits while maintaining the pump headat a constant value.
