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, 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.
