Robertshaw 720-050 Gas Valve

The Robertshaw 720-050 Gas Valve is a technical-grade, lever-actuated control engineered specifically for intermittent pilot ignition and hot surface ignition (HSI) systems. This 24V AC dual-valve assembly is the direct 722-052 replacement, designed to streamline field service for residential boilers, wall heaters, and central heating units. With a compact 3-9/16" swing radius, this 1/2 inch gas valve fits tight OEM footprints where standard valves may fail to clear internal housing. It features a slow opening characteristic for soft ignition, reducing burner noise and mechanical stress during start-up. The unit is factory-configured for Natural Gas at a 3.5" W.C. setpoint but includes a Uni-Kit for field conversion to LP Gas (11.0" W.C.). The intermittent pilot gas valve architecture incorporates a manual selector, dual automatic valves, and a pilot adjustment, ensuring precise fuel regulation for systems requiring a 150,000 BTU capacity.

• Universal Compatibility: Serves as a versatile HVAC replacement part for multiple Robertshaw and Rheem 60-22525-06 configurations.
• Multi-Position Mounting: Qualified for installation in any orientation (excluding upside down) to accommodate diverse furnace geometries.
• Simplified Wiring: Features standard 1/4" quick-connect terminals and top-accessible adjustments for efficient field tuning.
• Convertible Design: The included LP conversion kit allows technicians to adapt the valve for Propane applications on-site.
• Contaminant Protection: Built-in inlet filtered screen prevents debris from fouling the 24V gas valve main operator.

Is the Robertshaw 720-050 compatible with standing pilot systems?
No, this model is specifically engineered for intermittent pilot and hot surface ignition. For constant pilot applications, a 700 series manual or millivolt valve is typically required.

Can I use this valve for a 3/4" pipe installation?
The 720-050 features 1/2" NPT inlets and outlets. If your manifold uses 3/4" piping, you must use appropriate bushings or select the 720 series model with native 3/4" threading.

Does this unit come prepared for Propane?
It is factory-set for Natural Gas. To use it with LP, you must install the regulator spring and hardware provided in the Uni-Kit included in the box.
