Description
The Field Controls GVD-9PL 9 inch Automatic Vent Damper regulates flue gas flow by opening during burner operation and closing when the system is idle to reduce heat loss. Operating on 24V control, it uses an internal motorized mechanism to position the damper blade in response to call-for-heat signals. Mounted within the vent piping of gas-fired heating equipment in HVAC systems such as furnaces and boilers, it fits inline without a wiring harness for direct field connection. This component improves heat retention, supports combustion efficiency, and supports maintaining consistent system operation. UPC 090747580155 is associated with identification and compatibility.
