Lochinvar & A.O. Smith 100208603 Actuator
The Lochinvar & A.O. Smith 100208603 Actuator is a critical 3-way valve actuator engineered for precise fluid diversion and temperature regulation in high-efficiency hydronic systems. Designed as a direct replacement for the obsolete Lochinvar VAL20048, this 24VAC motorized component provides the 50 in-lb torque necessary to manage flow between the heat exchanger and the DHW loop. For technicians servicing Smart System controlled boilers, this actuator ensures the 3-wire, 3-point floating control signals are translated into reliable mechanical rotation, maintaining tight temperature differentials and preventing short-cycling in demanding commercial and residential applications. The unit’s robust drive mechanism is rated for ambient temperatures up to 122°F, making it a dependable choice for mechanical rooms with high thermal loads. Proper installation of this OEM replacement part is essential for optimizing the seasonal efficiency of Lochinvar Copper-Fin II and compatible A.O. Smith water heating platforms.
Key Benefits:- Precision Flow Control: Delivers accurate 90-degree rotation to manage 3-way valve positioning, ensuring consistent hot water delivery and zone management.
- OEM Compatibility: Specifically engineered to interface with Smart System control boards, replacing older VAL20048 models without requiring field modifications.
- High-Torque Performance: Provides 50 in-lb (5.6 Nm) of torque, sufficient to overcome mineral buildup or high differential pressures within the valve body.
- Integrated Safety: Features a manual clutch release for emergency positioning and troubleshooting, protecting the internal gear train during service.
- Is this actuator compatible with my older Lochinvar boiler? This unit is the official successor to the Lochinvar 100208603 and VAL20048. It is commonly used in Copper-Fin II and Power-Fin series; always verify your specific model number before installation.
- What are the power requirements for this component? The 100208603 operates on a 24VAC supply and uses 3-wire floating control logic. Ensure your transformer has sufficient VA capacity to handle the 6VA peak load.
- Can I manually override the valve position? Yes, the actuator includes a clutch release button. Pro-Tip: Always disconnect power before engaging the clutch to prevent stripping the drive gears.
