Lochinvar & A.O. Smith 100208608 Gas Valve

The Lochinvar and A.O. Smith 100208608 Gas Valve is a critical combustion control component engineered for high-efficiency commercial water heaters and boilers. This 24V redundant gas valve is factory-set for Liquid Propane (LP), delivering a steady 4.6" WC manifold pressure to ensure optimal burner performance and thermal efficiency. Featuring 3/4" NPT inlet and outlet ports, this valve provides the necessary flow rate for high-BTU applications found in the Lochinvar Armor and Knight series. As a direct replacement for VAL2413 and VAL2413K, it ensures seamless integration with the existing control board and ignition sequence. This slow-opening gas valve design minimizes hard starts and pressure spikes, protecting the heat exchanger and burner assembly in demanding commercial environments. For contractors performing field maintenance, verifying the solenoid resistance and manifold pressure is essential for maintaining strict combustion tolerances and safe CO levels.

• Direct OEM Compatibility: Replaces 100208608, VAL2413, and VAL2413K without the need for piping modifications.
• Precise LP Regulation: Factory-calibrated to 4.6" Water Column specifically for Liquid Propane systems.
• Standardized Electrical Interfacing: Operates on a 24V AC circuit, compatible with standard Lochinvar and A.O. Smith integrated control modules.
• Heavy-Duty Construction: Features a rugged 3/4 inch NPT connection to handle high gas volume requirements in commercial heating loops.

Can this gas valve be converted from LP to Natural Gas (NG)?
This specific model is calibrated for LP gas. While some valves allow for spring conversion kits, it is recommended to use the dedicated NG gas valve equivalent to ensure the correct internal orifice sizing and pressure regulation for your specific Lochinvar or A.O. Smith unit.

What are the symptoms of a failing Lochinvar VAL2413K valve?
Common indicators include ignition failure lockout codes, intermittent flame loss, or high-pitched humming from the solenoid. Always verify that the 24V signal is reaching the valve during the ignition trial before determining the valve is defective.

What is the purpose of the slow-opening feature on this gas valve?
The slow-opening mechanism allows for a controlled release of gas to the burner, preventing delayed ignition or "booming" during the start-up cycle, which extends the life of the combustion chamber components.
