Replacement HVAC Part

The Field Controls GVD-7PL is a 7-inch automatic gas vent damper engineered for residential and commercial heating systems operating on 24 VAC, 60 Hz power. Constructed from stainless steel, this damper provides superior corrosion resistance and durability in demanding HVAC environments. The unit automatically regulates natural draft during appliance operation while sealing closed during off cycles to minimize heat loss, prevent conditioned air escape, and block cold air infiltration from downdrafts. Compatible with all 24 VAC, 60 Hz intermittent ignition and standing pilot systems, the damper opens and closes in approximately 15 seconds while consuming only 3 watts during operation with minimal power draw at rest. Dual integrated safety switches ensure the burner fires only when the damper is in the fully open position, providing reliable protection without interfering with existing appliance safety controls when properly installed. This replacement damper is ideal for furnace and boiler applications requiring efficient thermal management and enhanced system performance. The GVD-7PL meets industry standards for automatic vent damper operation and is suitable for retrofit installations requiring a direct replacement for original Field Controls equipment or compatible competitive models.
