Lochinvar & A.O. Smith 100172010 Gas Valve

The Lochinvar & A.O. Smith 100172010 Gas Valve, specifically the WB050 model, is a critical component for maintaining precise fuel regulation in residential and commercial boiler systems. Designed as a high-performance direct replacement gas valve for the obsolete Lochinvar VAL3208, this assembly ensures optimal air-to-gas ratios for efficient combustion. This HVAC gas control valve is engineered to work seamlessly with various Lochinvar Knight and A.O. Smith water heater configurations, providing the reliable gas flow modulation required for stable flame signals and consistent heat output. As an OEM replacement part, it meets the exact factory specifications for port sizing and electrical connector geometry, minimizing troubleshooting time during field installation. Properly functioning gas valves for boilers like the 100172010 are essential for preventing common lockouts such as "Ignition Failure" or "Flame Loss" errors, ensuring that the burner assembly receives the correct manifold pressure for safe operation in demanding heating environments.

• Broad Compatibility: Serves as a versatile 100172010 WB050 gas valve for specific Lochinvar and A.O. Smith boiler and water heater models.
• Precision Engineering: Accurately manages the gas flow to the burner, maintaining the strict air-gas mixtures required for high-efficiency systems.
• Enhanced Safety: Built to prevent gas leakage and ensure rapid shut-off during system safety faults or power loss.
• Simplified Maintenance: Designed for direct "drop-in" replacement, reducing the labor hours needed for HVAC gas valve troubleshooting and repair.

What are the signs that my Lochinvar 100172010 gas valve needs replacement?
Technicians typically look for signs such as the unit failing to ignite despite a strong spark, consistent "Flame Loss" error codes, or the smell of gas near the burner assembly. If the valve fails to open when receiving the correct voltage from the control board, a mechanical internal failure is likely.

Is the 100172010 a direct replacement for the VAL3208?
Yes, the 100172010 is the designated manufacturer-approved replacement for the now-obsolete VAL3208 gas valve. It maintains the same physical dimensions and electrical requirements to ensure 100% compatibility with existing WB050 series equipment.

Can this gas valve be used for both Natural Gas and Liquid Propane systems?
The valve is typically factory-configured for specific fuel types. You must verify the orifice and spring kit requirements based on the fuel source of the boiler to ensure the manifold pressure is set correctly for either NG or LP applications.
