Taco 006-BC7-4IFC Bronze Circulator W/Integral Flow Check & Relay 3/4" Sweat

The Taco 006-BC7-4IFC is a small device that has three essential components for hydronic heating and cooling systems: a circulation loop, a flow check, and a pressure relief valve. Its 3/4-inch diameter allows for multiple applications. Even when a pump or zone valve is off, the circulation loop, often referred to as a bypass loop, makes sure that water or a water-glycol combination flows continuously through the system. This keeps certain zones from freezing or overheating. Water cannot flow in the opposite direction to the integrated flow check, which preserves the efficiency and correct operation of the system.
