Bypass valves from Grainger provide an accurate and dependable means of controlling excess flow in zone valve systems. 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.
