Allied Air 72w34 Modulating Gas Valve Natural Gas 24 Vac

Product Description

The ALLIED AIR 72w34 is a modulating gas valve designed for natural gas heating systems. It operates on a 24 VAC control signal and features a 1/2 inch inlet and 1/2 inch outlet connection. Modulating valves regulate gas flow across a range of firing rates rather than simple on/off switching, which allows the burner to match heat output more closely to the system demand. This valve is a direct-fit component installed by licensed HVAC technicians during new equipment installation or field replacement of a failed gas valve assembly.

This valve is suited for residential and light commercial gas furnace applications where modulating burner control is required. The modulating design supports variable-capacity operation, making it appropriate for high-efficiency furnace systems that stage or continuously vary heat output. Installation typically involves integration with a compatible furnace control board and gas train that support modulating valve operation.

Key Features

• Modulating operation allows variable gas flow for precise burner output control
• Compatible with natural gas fuel supply
• 24 VAC control signal for integration with standard low-voltage furnace control boards
• 1/2 inch inlet and 1/2 inch outlet connections for straightforward in-line installation
• Compact form factor suitable for tight furnace cabinet installations

Compatibility

Designed as an OEM-style modulating gas valve replacement for natural gas furnace systems requiring a 24 VAC, 1/2 inch inlet by 1/2 inch outlet valve. Refer to the original equipment documentation and cross-reference part number 103016-01 to confirm fitment before installation.

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 IFGC. Shut off the gas supply at the service valve and disconnect power to the furnace control circuit before removing the existing valve. Verify all threaded connections are properly sealed with approved thread compound rated for gas service, and leak-test all joints with approved solution before restoring gas flow. Do not apply thread sealant to the first thread of any fitting.
