True or False: A balancing valve completely shut off will result in no water flow in the radiator.

A balancing valve that is completely shut off will not allow water to flow through the system it regulates. However, the statement's assertion implies that a radiator, which relies on a specific flow of water for effective heating, would entirely stop functioning if the balancing valve is closed. In reality, while the radiator may not receive the intended flow, some residual flow may continue due to pressure differentials or other design factors. Thus, the assertion that no water flow occurs at all is not entirely accurate, making the answer false. Proper understanding of how balancing valves function and their role in hydronic systems clarifies this nuance, indicating that if fully closed, the valve would primarily restrict flow but does not necessarily eliminate all flow entirely under specific circumstances.
