The Taco differential bypass valve provides an accurate and dependable means of controlling excess flow in zone valve systems that can be created when there is a reduction in the demand for heat. This reduced heat demand typically occurs as zone thermostats are satisfied and their corresponding zone valves close, causing the system pump to attempt to force more water through the remaining zones. Differential bypass valves should also be used to prevent dead heading of the circulator in systems where parallel piped heat emitters are controlled by thermostatic radiator valves As zone valves close, instead of forcing more water through the remaining open zones, the differential bypass valve automatically reroutes the excess flow through the bypass valve. This prevents velocity noise while maintaining the designed heat transfer of each zone, enhancing overall system performance.
