ASCO 8215B80-24V 2 Inch N/C Shutoff Valve 0-25 Psi

The ASCO 8215B80-24V is a 2-inch normally closed cutoff valve that controls the flow of fluids and gases in HVAC systems. It runs on a 24-volt DC power supply and has a 2-inch diameter opening. When no power is supplied, the valve remains closed, preventing flow. When it gets a 24-volt signal, the valve opens and flow resumes. The ASCO 8215B80-24V's N/C design makes it appropriate for fail-safe applications, in which the valve automatically closes in the case of a power failure, avoiding accidental flow. This feature is critical in HVAC equipment such as chillers, boilers, and air handling units, where precise control and safety of fluid flow are required.
