A number of stores carry Honeywell gas valve parts, including Grainger.com and SupplyHouse.com. Owners can also order parts directly from the manufacturer by visiting YourHome.Honeywell.com.
Gas valves regulate the flow of natural gas or liquid propane in a heating system. The three most common types of gas valves are standing pilot, slow-opening and step-opening.
Gas valves vary in the amount of fuel they can regulate, as well as the size of their inlet and outlet fittings. The valves must be specifically designed for the type of fuel the heating system uses. Owners can use conversion kits to align a particular valve to a specific fuel system.
