Lochinvar Gas Valve/Venturi Assembly

The Lochinvar Gas Valve/Venturi Assembly (also called a gas valve and venturi assembly or gas train valve) is a replacement combustion-control component for Lochinvar water heaters and boilers. It regulates gas flow and draws in combustion air. This creates the correct air-fuel mixture for stable ignition and efficient burner operation.

Key Features:

• Combines a gas regulating valve with a venturi mixer in one assembly
• Helps maintain a consistent air-to-fuel ratio for steady combustion and heating performance
• Supports efficient fuel use and cleaner combustion
• Built for residential and commercial water heating and boiler applications
• Genuine OEM-style replacement for restoring factory operation

Service Tips: Inspect the valve and venturi for debris buildup and gas leaks during routine service. Always shut off the gas supply before servicing. Check gas pressure and combustion settings after installation.

Lochinvar has focused on energy-efficient water heating and boiler products since 1939. A matching replacement gas valve/venturi assembly helps keep your system running reliably and safely.
