Automatic Butterfly Valve With Half Moon Stops -AC Voltage

Ductwork butterfly valves are designed to assist with air-flow rate changes. An electronic solenoid controls a pneumatic cylinder that pivots a circular disk mounted in the airstream to control airflow from fully open (for 100% flow), to fully closed (shutting off all air). 90 PSI is required to operate the pneumatic cylinder. The cylinder is activated by solenoids connected to virtually any electric signal - 12/24 V, AC/DC, or 110/220 voltage. 3/16" thick disk offers long life. Also known as Butterfly Damper, Butterfly Valve or Volume Damper Diameters are +/- 1/8 inch. Looking for DC Voltage? Click here.
