Robertshaw 720-472 Gas Valve

The Robertshaw 720-472 is a robust 24V step-opening gas valve designed for high-performance heating applications. Featuring a 1/2" NPT inlet and outlet, this dual-voltage operator provides a regulated 3.5" W.C. natural gas output, ensuring consistent manifold pressure for efficient combustion. This model is the direct replacement for the 7200ERCS-2, engineered for versatility in intermittent pilot ignition systems. The 720 series accommodates multiple mounting positions, offering flexibility for tight furnace cabinets or rooftop units. With a capacity of up to 150,000 BTU, it handles standard residential and light commercial loads with ease. Field technicians prefer this valve for its reliable solenoid-actuated design and terminal connections that simplify gas valve troubleshooting. Its step-opening regulation provides a quieter ignition sequence, reducing initial burner noise and thermal stress on the heat exchanger. This Robertshaw gas valve is a staple for contractors maintaining older systems requiring precise furnace gas valve replacement components.

• Direct Replacement: Specifically engineered to replace the outdated 7200ERCS-2 without manifold modifications.
• Universal Mounting: Can be installed in any position (except upside down) to accommodate various HVAC gas valve wiring configurations.
• Step-Opening Ignition: Enhances equipment longevity by easing the initial gas flow for a smoother light-off.
• Broad Compatibility: Works seamlessly with most 24V intermittent pilot or hot surface ignition control modules.

What is the difference between the 720-472 and the 7200ERCS-2?
The 720-472 is the current manufacturing standard and functional equivalent to the 7200ERCS-2, featuring improved internals while maintaining identical physical dimensions and gas valve specifications.

Can this valve be converted to LP (Liquid Propane)?
Yes, this is a convertible gas regulator. While it ships setup for Natural Gas, it can be converted using the appropriate Robertshaw conversion kit for high-pressure LP applications.

What are the electrical requirements for this unit?
This valve operates on a standard 24V AC, 50/60 Hz circuit, drawing approximately 0.5 Amps during operation.
