VCD-23 - Greenheck
Application and DesignThe VCD-23 series is a ruggedly built low leakage control damper intended for application in low to medium pressure and velocity systems. A wide range of electric and pneumatic actuators are (See page 4 for specific limitations) Pressure: Up to in. wg ( kPa) - pressure differential Velocity: Up to 3000 fpm ( m/s) Leakage: Class 1A @ 1 in. wg (.25 kPa) Class 1 @ up to 5 in. wg ( kPa) Temperature: Up to 250 F (121 C) (Consult Greenheck for higher temperatures)* W&H dimension furnished approximately 1/4 in. (6mm) with optional extension pin and standoff bracket.
