Ao Smith 100074624 Flow Adjust Flow Sensor Valve for Water Heaters and Boilers

Product Description

The AO Smith 100074624 is a Flow Adjust and Flow Sensor Valve designed for use in water heaters and boilers. This valve serves two critical functions in a hydronic or domestic hot water system: it regulates the flow rate of water passing through the system, and it monitors that flow to ensure proper operation. Water heater and boiler technicians rely on components like this to keep heating systems running safely and efficiently. When water flow is too low, a boiler or water heater can overheat, causing equipment damage or premature failure. When flow is too high, the system may not heat water to the correct setpoint, leading to inconsistent temperatures and wasted energy. The AO Smith 100074624 addresses both problems by combining flow adjustment and flow sensing into a single valve assembly. This reduces the number of components needed in the system and simplifies installation and troubleshooting. HVAC technicians and plumbers working on Lochinvar and AO Smith residential or commercial heating equipment will find this valve to be a direct OEM replacement part. Using an OEM part ensures correct fit, proper calibration, and compatibility with the existing control board and safety systems. Flow sensor valves like this one send a signal to the control system confirming adequate water circulation before the burner is allowed to fire, which is a key safety feature in modern water heaters and boilers. The valve weighs 0.42 pounds, making it a lightweight component that is easy to handle during service calls. Keeping this part on hand can reduce equipment downtime and help technicians complete repairs on the first visit.
