For a 24-volt standing-pilot replacement, start by matching the existing valve’s model, voltage, gas type, connection sizes, and control arrangement. The Honeywell VR8200A2744 and Robertshaw 700-406 are explicitly identified as 24-volt standing-pilot or combination valves; the White-Rodgers 36C03-300 is listed as a 24 VAC standing-pilot valve. The millivolt MCAMPAS valve is not a 24-volt substitute. The Robertshaw 720-472 is a 24-volt step-open valve, but its listing does not establish standing-pilot compatibility.

|---|---|---|
| Honeywell VR8200A2744 | Buyers matching a single-stage, 24 VAC standing-pilot valve | Standard opening |
| White-Rodgers 36C03-300 | Buyers needing a 24 VAC standing-pilot valve with an LP kit listed | 1/2-inch by 3/4-inch connections |
| Robertshaw 700-406 | Buyers replacing the same 24-volt combination-valve model | 3/4-inch inlet and outlet |
| Robertshaw 720-472 | Buyers whose equipment specifies this step-open valve | 24-volt step-open, convertible regulator designation |
| MCAMPAS 700-506 | Buyers seeking a compatible millivolt-only replacement | Not compatible with 24-volt 700-series valves |
Honeywell VR8200A2744 Standing Pilot Valve
The Honeywell VR8200A2744 is listed as a single-stage, 24 VAC, standard-opening standing-pilot gas valve. The product name also gives its approximate dimensions as 5.1 by 3.6 by 4.2 inches. Those details make it a relevant candidate when a system calls for a 24-volt valve with this control style and opening description.
Best for: Buyers replacing a single-stage, 24 VAC standing-pilot valve and confirming the VR8200A2744 model against the equipment documentation. It was selected because the listing directly identifies both the voltage and standing-pilot design.
Check before ordering: The supplied product information does not state connection sizes, gas type, or other installation specifications. Do not assume these match the existing valve based only on voltage and pilot style. Verify the full model and installation requirements before purchase.
White-Rodgers 36C03-300 24 VAC Valve
The White-Rodgers 36C03-300 is described as a 24 VAC standing-pilot gas valve with an LP kit. Its listed connections are 1/2 inch by 3/4 inch. This combination of voltage, pilot type, and connection information helps buyers compare it with an existing valve, but it does not by itself confirm that it fits a particular furnace or appliance.
Best for: Buyers whose equipment calls for a 24 VAC standing-pilot valve and whose required connection sizes align with the listed 1/2-inch and 3/4-inch connections. It was selected because the product name explicitly identifies the electrical rating and pilot type.
Check before ordering: Although an LP kit is listed, confirm the required fuel configuration and whether the included kit is appropriate for the appliance. The available product details do not specify additional operating characteristics or confirm compatibility with a particular system.
Robertshaw 700-406 24-Volt Combination Valve
The Robertshaw 700-406 is identified as a 24-volt combination gas valve with a 3/4-inch inlet and a 3/4-inch outlet. That makes it a candidate for buyers replacing this exact model or following equipment documentation that specifies it. Its listing provides a model number and port sizes, but not enough information to establish suitability for every standing-pilot appliance.
Best for: Buyers matching a Robertshaw 700-406 or a documented replacement requirement for that specific 24-volt combination valve. It was selected because the model number, voltage, and connection sizes are clearly stated.
Check before ordering: The listing information provided does not describe pilot arrangement, fuel type, or other specifications. Do not treat the shared “700” series number as proof of interchangeability with a different valve. Verify the exact part number and system requirements.
Robertshaw 720-472 Step-Open Valve
The Robertshaw 720-472 is listed as a 24-volt step-open valve with a convertible regulator and a 1/2-inch designation. It is included as a possible match for buyers whose equipment documentation specifies this exact valve or valve type. “Step-open” is a distinct operating description; it should not be assumed to mean the same thing as a standard-opening valve.
Best for: Buyers checking a replacement requirement for the 720-472 or a 24-volt step-open convertible-regulator valve. It was selected because its listed voltage and operating description are relevant to 24-volt gas valve searches.
Check before ordering: The product information supplied does not state that this is a standing-pilot valve. Avoid choosing it solely because it is 24 volts; confirm the pilot arrangement, connection details, and equipment compatibility in the manufacturer’s documentation.
MCAMPAS 700-506 Millivolt Gas Valve
The MCAMPAS 700-506 is a millivolt-only valve, not a 24-volt replacement. Its listed electrical operating range is 250 to 750 millivolts, and the description says it works with a two-lead thermopile and a standing-pilot 1/4-inch tube. It is listed for natural gas with a 4-inch water-column outlet pressure and a 200,000 BTU rating in the product name.
Best for: Buyers who have confirmed that their system uses a compatible millivolt Robertshaw 700-series valve, such as a listed 700-506 replacement. It was selected to clarify an important near-match in search results and to help prevent a voltage mismatch.
Check before ordering: The product description explicitly says it is not compatible with Robertshaw 700-series 24-volt combination valves, including 700-402, 700-406, and 700-426. Avoid this option for a 24-volt system.
Buying Guide: How to Choose a 24-Volt Standing-Pilot Gas Valve
A gas valve is not interchangeable merely because its voltage appears to match. Confirm the complete model number and required specifications using the appliance label, service documentation, or guidance from a qualified technician. A standing-pilot system, a millivolt control, and a 24-volt control use different electrical arrangements. Choosing the wrong type can prevent proper operation or create an unsafe installation.
Does the existing valve use 24 volts or millivolts?
Start with the electrical rating on the existing valve and the appliance documentation. The Honeywell VR8200A2744, White-Rodgers 36C03-300, Robertshaw 700-406, and Robertshaw 720-472 product names identify 24-volt or 24 VAC specifications. The MCAMPAS 700-506 is specified for millivolt operation. These ratings are not interchangeable; the MCAMPAS listing specifically warns against using it with 24-volt Robertshaw combination valves.
Also distinguish the valve’s supply voltage from the standing-pilot description. “Standing pilot” refers to a pilot flame that remains lit during normal operation, while “24 VAC” describes an electrical control rating. A product should match both the equipment’s pilot arrangement and its electrical requirements.
What model number and connection sizes must match?
Record the full model number before shopping. A shared brand name or product-family number is not enough to establish that two valves are interchangeable. For example, the supplied MCAMPAS listing identifies some millivolt 700-series replacements but explicitly excludes several 24-volt combination models. The Robertshaw 700-406 listing specifies 3/4-inch inlet and outlet connections, while the White-Rodgers listing gives 1/2-inch by 3/4-inch connections.
Compare connection sizes and the physical arrangement required by the appliance. The Honeywell listing provides dimensions, but the supplied details do not provide its connection sizes. If a specification is missing, verify it through the manufacturer’s documentation rather than inferring it from a photo or another model in the same series.
Does the gas type and pressure specification match?
Check whether the appliance is configured for natural gas or LP gas and confirm that the selected valve is approved for the required configuration. The MCAMPAS 700-506 product details identify natural gas and a 4-inch water-column outlet pressure. The White-Rodgers product name mentions an LP kit, but that alone does not prove the kit suits a particular appliance or conversion.
When comparing specifications, use the appliance’s stated requirements rather than assuming that similar-looking valves have the same pressure settings. Confirm any regulator setting or fuel conversion requirements before installation. If the listing does not provide a needed specification, treat that as a reason to verify, not a reason to guess.
Is the valve standard-opening or step-open?
Opening behavior matters when replacing a valve. The Honeywell VR8200A2744 is listed as standard opening, whereas the Robertshaw 720-472 is labeled step-open. Those descriptions are not interchangeable. Choose a step-open valve only when the appliance documentation or existing valve specification calls for that type.
The supplied information does not identify the Robertshaw 720-472 as a standing-pilot valve. Its 24-volt rating alone is not enough to make it a suitable match. Confirm pilot style and the exact control sequence before considering it as a replacement.
When should a qualified professional handle the replacement?
Gas valve replacement involves fuel connections and an appliance’s safety controls. Use the appliance manufacturer’s service instructions and applicable local requirements, and consult a qualified professional if you are not trained to work on gas equipment. Do not modify gas piping or bypass safety controls to make a valve fit. After any service, the appliance must be checked according to its instructions for safe operation and leaks.
Before ordering, gather the appliance make and model, the existing valve’s full part number, the electrical rating, fuel type, connection sizes, and any specified opening or pilot characteristics. This checklist can narrow the selection more reliably than searching by “24 volt standing pilot” alone.
Frequently Asked Questions
Can a millivolt gas valve replace a 24-volt valve?
No. Millivolt and 24-volt valves have different electrical requirements. The MCAMPAS 700-506 listing identifies it as millivolt-only and specifically excludes certain 24-volt Robertshaw combination valves.
Is every 24-volt gas valve suitable for a standing-pilot system?
No. Voltage does not confirm pilot arrangement or opening type. Check the exact valve model and the appliance documentation. The Robertshaw 720-472 listing identifies a 24-volt step-open valve but does not establish that it is a standing-pilot model.
Which listed product explicitly says standing pilot?
The Honeywell VR8200A2744 and White-Rodgers 36C03-300 product names explicitly identify standing-pilot operation. The MCAMPAS 700-506 details mention a standing-pilot tube, but that valve is millivolt-only, not a 24-volt replacement.
Can I choose a valve based only on inlet and outlet size?
No. Matching pipe sizes does not establish electrical, fuel, pilot, pressure, or control compatibility. Match the complete valve specification to the appliance.
What information should I collect before buying?
Record the existing valve’s complete model number, voltage, fuel type, connection sizes, pilot arrangement, and any specified regulator or opening characteristics. Confirm missing details with the appliance documentation or a qualified professional.
