SchneiderAL-181 Air Valve 1/4 Inch Barb 0.3 Scfm 120V

The Schneider Electric (Barber Colman) AL-181 is a 1/4 inch, 120V solenoid air valve designed to control the flow of natural gas in HVAC systems. Solenoid valves use an electromagnetic coil to open or close a valve in response to an electrical signal. When energized, the coil creates a magnetic field that opens the valve, allowing natural gas to flow through. When de-energized, the valve closes, stopping the flow of gas. In HVAC equipment like furnaces and boilers, the AL-181 is typically used to regulate the gas supply to burners, ensuring proper heating output. This precise control offers several benefits, including: efficient operation by optimizing burner performance, improved safety by automatically shutting off gas in case of electrical issues, and consistent temperature control within your building.
