Trane VAL9033 Gas Valve

The Trane VAL9033 Gas Valve is a professional-grade 24V control engineered for high-reliability fuel regulation in residential and light commercial forced-air systems. This Natural Gas (NG) furnace valve features a standard 1/2 inch NPT inlet/outlet, ensuring seamless integration with existing manifold piping. Designed as a direct OEM replacement gas valve, the VAL9033 eliminates the mounting and wiring hurdles often found with universal alternatives. Running on a 24VAC coil at 50/60Hz, it provides precise opening characteristics necessary for stable combustion and efficient heat exchange. Field technicians prefer this model for its robust internal solenoid and consistent pressure regulation, which are critical for maintaining manifold pressure at the 3.5" W.C. standard. Whether you are performing a mid-season emergency swap or a full system overhaul, the VAL9033 natural gas control offers the exact specifications required to restore factory-standard performance and safety to the burner assembly.

• Precise Fuel Regulation: Maintains consistent manifold pressure to prevent delayed ignition or soot buildup.
• Fast-Opening Operation: Engineered for quick response times during the furnace's trial for ignition sequence.
• OEM Compatibility: Replaces specific Trane and American Standard gas valves without the need for additional bracketry or manifold modifications.
• Standardized Connections: Utilizes 1/2" NPT threading and standard 1/4" spade terminals for 24V control wiring.
• High-Durability internal components: Designed to withstand micro-stresses and contaminants commonly found in natural gas lines.

Is the VAL9033 compatible with Propane (LP) systems?
This specific model is a Natural Gas valve. For LP applications, a conversion kit with the correct spring and orifices must be installed according to the manufacturer's manifold pressure requirements.

What are the signs of a failing VAL9033 gas valve?
Contractors typically look for a 24V signal at the coil with no gas flow, audible clicking without ignition, or a "sticky" valve that requires physical tapping to open—often caused by internal sediment or solenoid fatigue.

Does this valve include a pressure regulator?
Yes, the VAL9033 includes an integrated pressure regulator that is factory-set but adjustable to ensure the burners receive the correct BTU input for the specific heat exchanger design.
