Lochinvar & A.O. Smith 100093823 Valve

The Lochinvar & A.O. Smith 100093823 Valve is a direct OEM replacement engineered for high-performance gas regulation in specific residential and commercial heating units. This liquid propane (LP) gas valve is factory-calibrated to a 10" water column (WC) manifold pressure, ensuring precise fuel delivery to the burner assembly. Featuring a standard 1/2" NPT inlet/outlet, this mechanical component facilitates high-reliability flow control and is a critical part for maintaining the safety and efficiency of A.O. Smith and Lochinvar water heaters. As a genuine factory repair part, it replaces discontinued or obsolete part numbers including 9006604005 and 6910830, providing a seamless fit without the need for field modifications. This valve is designed to handle the high energy density of propane, offering stable pressure regulation to prevent overheating or incomplete combustion in LP gas water heaters.

• Precise Pressure Regulation: Pre-set to 10" WC for optimized LP gas combustion and consistent thermal output.
• Direct OEM Compatibility: Engineered specifically for Lochinvar and A.O. Smith systems, replacing outdated models 9006604005 and 6910830.
• Heavy-Duty Construction: Manufactured with high-grade materials to withstand the rigors of HVACR environments and industrial gas control.
• Seamless Integration: Features standard 1/2 inch gas line threading for straightforward installation in existing supply manifolds.
• Enhanced Safety: Built to rigorous factory standards to ensure dependable shut-off and gas flow modulation for propane-fired appliances.

Is this valve a universal fit for all A.O. Smith water heaters?
No, the 100093823 gas valve is not universal. It is specifically designed for liquid propane (LP) models that require 10" WC and a 1/2" connection. Always verify the part number against your unit’s data plate.

Can I use this gas valve for a natural gas conversion?
This specific part is calibrated for LP gas only. Using an LP gas control valve on a natural gas system without a proper conversion kit and recalibration can lead to hazardous operating conditions.

What are the signs that my current 100093823 valve needs replacement?
Common indicators include the pilot failing to stay lit despite a healthy thermopile voltage, erratic manifold pressure, or no gas flow reaching the main burner during a call for heat.
