Description
The York S1-VR8204M1026 1/2″ Natural Gas Valve is a gas control unit used to regulate and control the flow of natural gas into a furnace or heating system burner. It is used to open and close gas supply based on thermostat demand and protective circuit signals, allowing for controlled ignition, stable flame formation, and proper burner operation in heating equipment. It is placed where precise fuel flow is required for combustion in HVAC systems. It works with the ignition control board and flame sensor to manage sequencing, maintain proper fuel flow, and shut off gas supply during fault conditions.
