American Standard VAL07973 Single Stage Combo Gas Valve

Product Description

The AMERICAN STANDARD VAL07973 is a genuine OEM single-stage combination gas valve designed for use in natural gas furnace systems. It operates on 24 volts and features a 0.5-inch NPTI inlet and 0.5-inch outlet connection, making it a direct-fit replacement in compatible American Standard and Trane gas furnace applications. The valve is fast-acting and combines multiple gas control functions into a single unit, reducing installation complexity. At 5 pounds, it is a solid, production-grade component intended for installation by licensed HVAC technicians servicing residential and light commercial heating equipment.

This gas valve is commonly found in various American Standard and Trane gas furnace systems. It serves as a verified supersession for several older part numbers including VAL07215, VAL06526, and VAL03339, allowing technicians to consolidate replacement inventory across multiple service calls. The combo-style design integrates the pressure regulator and redundant safety shutoff functions typical of modern single-stage furnace gas trains, making it appropriate for both scheduled maintenance replacements and emergency service situations.
