Nordyne 624494R Gas Valve

The Nordyne 624494R Gas Valve is a critical OEM component designed for high-efficiency natural gas furnaces and heating units. This 24V slow open gas valve is engineered to deliver a controlled manifold pressure of 3.5" WC, ensuring smooth ignition and stable burner performance. As a direct 48G30 replacement valve, it maintains factory specifications for safe terminal connections and port alignment, streamlining the swap-out process for field technicians. The 1/2" NPT inlet and outlet design facilitates a secure fit within standard gas manifolds, while the slow-opening feature prevents hard starts and protects the heat exchanger from thermal shock. For contractors servicing Nordyne, Miller, or Intertherm equipment, utilizing this genuine Nordyne replacement part ensures the system operates at its calibrated natural gas manifold pressure without the need for extensive field modifications. This robust solenoid valve is the industry standard for maintaining reliable combustion mid-cycle and during initial startup sequences.

• Direct OEM Compatibility: Serves as an exact drop-in 624494R is identical to 48G30, ensuring zero-clearance issues during installation.
• Precision Pressure Regulation: Factory-set at 3.5" WC Nat to meet strict furnace output requirements and optimize fuel efficiency.
• Enhanced Safety: The 24V slow open mechanism provides a gradual ramp-up of gas flow, reducing combustion noise and mechanical stress.
• Standardized Infrastructure: Robust 1/2" Gas Valve threading allows for standard wrench-tight connections without specialized adapters.

Is the 624494R compatible with LP (Propane) systems?
This specific model is calibrated for 3.5" WC Natural Gas. For liquid propane applications, a dedicated conversion kit or an LP-specific valve must be used to ensure the correct burner pressure.

Can I use this to replace a fast-opening valve?
Technicians often prefer the Nordyne 624494R slow-open timing to mitigate "booming" during ignition. Check the original equipment manufacturer (OEM) submittal data to confirm that the slow-open characteristic matches your furnace's sequence of operation.

What are the electrical requirements for this solenoid?
This is a standard 24V HVAC gas valve. Ensure your transformer provides a consistent 24VAC signal to the terminals to prevent solenoid chatter or failure to pull in.
