Allied Air 74w26 Natural Gas Valve 24V 1/2 in Npt

Product Description

The ALLIED AIR 74w26 is a natural gas valve designed for reliable flow control in gas-fired heating systems. Operating at 24 volts AC, it features a 1/2-inch NPT inlet connection and a 1/4-inch hose barb port, making it suited for both new installations and retrofit applications. This valve provides precise shutoff and flow regulation as part of a furnace or boiler gas train. Licensed HVAC technicians and gas fitters are the primary trade installers for this component in residential and light commercial settings.

This valve is appropriate for use in residential and commercial gas heating systems where a 24-volt control circuit governs burner operation. The 1/2-inch NPT connection is a standard size found in many gas appliance inlet configurations. The 1/4-inch hose barb port accommodates pressure tap or test gauge connections during commissioning and service. It is suited for new construction installs, equipment retrofits, and service replacement work on gas furnaces and similar appliances.

Key Features

• 24-volt AC coil voltage compatible with standard furnace low-voltage control circuits
• 1/2-inch NPT inlet for standard gas line connections
• 1/4-inch hose barb port for pressure testing or auxiliary connections
• Rated for natural gas service

Compatibility

Designed as an OEM-style replacement gas valve for residential and commercial gas-fired heating equipment requiring a 24-volt, 1/2-inch NPT natural gas valve.

Installation Notes

Installation must be performed by a licensed HVAC technician or gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the main gas supply and de-energize the unit at the disconnect before beginning work. Verify inlet and outlet connections are leak-free using an approved gas leak detection solution after installation. Do not attempt to adjust internal valve components or bypass the valve's safety shutoff function.
