Selecting the right duct material is critical for chemical and wastewater applications where corrosive fumes, moisture, and harsh operating conditions can shorten system life. This guide compares galvanized steel, stainless steel, and flanged ductwork, helping engineers, contractors, and plant managers choose the best solution for long-term performance, reliability, and corrosion resistance.
Automatic Butterfly Valve With Half Moon Stops -DC 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, 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.
