Robertshaw 710-402 Gas Valve

The Robertshaw 710-402 is a versatile, low-capacity millivolt gas valve engineered for precision fuel control in intermittent pilot ignition and standing pilot systems. Designed for high-reliability in residential and light commercial heating applications, this valve features a 1/2 inch NPT inlet and a 1/2 inch NPT outlet, with a 90-degree side outlet configuration for simplified installation in tight furnace or boiler cabinets. Operating on a 24VAC or 12VDC dual-voltage coil, it maintains a factory-set 3.5" WC manifold pressure. Technical specifications include a high-flow capacity of up to 150,000 BTU/HR and a multi-position mounting capability, allowing for installation at any angle from 0° to 90° from upright. This universal replacement gas valve is a compatible direct-fit solution for many OEM components, ensuring stable pilot gas regulation and consistent burner sequencing under varying inlet pressures.

• Universal Compatibility: Serves as a primary service replacement for numerous 710 series models, reducing truck stock requirements.
• Dual Voltage Versatility: Field-proven 24V/12V electrical rating allows for integration into diverse control circuits.
• Precise Regulation: Integrated pressure regulator ensures stable 3.5" Water Column output for optimal combustion efficiency.
• Flexible Installation: Compact footprint and multi-position mounting capabilities accommodate restricted service clearances.

Common Technical Questions

Can I use this valve for propane/LP conversions?
The Robertshaw 710-402 is factory-set for Natural Gas. To utilize it with Liquid Propane, an LP conversion kit must be installed to adjust the orifice and regulator spring accordingly.

Does this valve support 100% shut-off?
Yes, this model includes a built-in safety magnet for 100% shut-off of both main and pilot gas should the thermocouple signal drop below the required millivolt threshold.

What is the maximum BTU rating for this component?
This 1/2" gas valve is rated for a 150,000 BTU capacity, making it suitable for most standard residential furnaces and small boiler units.
