Robertshaw 710-402 Gas Valve 0.5 Inch 24 Vac 12 Vdc

Product Description

The ROBERTSHAW 710-402 is a combination gas valve designed for use in residential and light-commercial gas-fired appliances. It controls the flow of gas from the supply line to the burner assembly, providing the on/off and pressure-regulation functions required for safe ignition and steady operation. The valve operates on 24 volts AC or 12 volts DC, making it compatible with standard low-voltage control systems used in furnaces, boilers, and similar heating equipment. Inlet pressure is rated at 3.5 inches water column (WC), suitable for natural gas residential supply conditions. The metal body construction provides durability in sustained heating-cycle service. Licensed HVAC technicians are the typical installers for this component.

The 710-402 is suited for residential gas furnaces, boilers, water heaters, and other appliances that use a 0.5-inch gas valve with low-voltage actuation. It fits installations where the control circuit operates at 24 VAC from a standard furnace transformer or at 12 VDC in certain appliance configurations. This valve is appropriate for service-replacement and new-installation applications in natural gas systems operating at standard residential inlet pressures.

Key Features

• Dual-voltage operation: 24 VAC or 12 VDC coil actuation
• 0.5-inch pipe connection for standard residential gas supply lines
• 3.5 inches WC inlet pressure rating for natural gas service
• Metal body construction for durability in continuous heating-cycle applications
• Combination valve design integrates on/off control and pressure regulation in one assembly

Compatibility

Designed as an OEM-style replacement gas valve for residential and light-commercial gas-fired appliances requiring a 0.5-inch, 24 VAC or 12 VDC combination valve at 3.5 inches WC inlet pressure.

Installation Notes

Gas valve replacement must be performed by a licensed HVAC technician or qualified gas service professional in accordance with local codes and the appliance manufacturer instructions. Shut off the gas supply and disconnect electrical power to the appliance before beginning any service work. Leak-test all gas connections with an approved leak-detection solution after installation before restoring gas flow or power. Follow applicable codes including the International Fuel Gas Code (IFGC) for piping and valve installation requirements.
