White-Rodgers 36C74-205 Manifold Gas Valve

The White-Rodgers 36C74-205 Manifold Gas Valve precisely modulates natural gas flow in residential and commercial gas-fired heating systems, delivering reliable fuel shutoff and regulation for burners and combustion equipment. This 24 VAC, slow-opening valve is part of the White-Rodgers 36C Series and is designed for inline installation with a 3/4 inch inlet/outlet, including reducer bushings 3/4" x 1/2" and 1/2" x 3/8" to simplify piping configurations. It supports both hot surface ignition and direct spark ignition applications and is commonly used in furnaces, rooftop HVAC units, unit heaters, and packaged heating systems where safe, consistent combustion control is critical. Common replacements include Honeywell VR8205, Robertshaw 7000 Series, and Emerson 36C74-431 gas valves.
