Straight Single Clapper Fire Department Connection

SANJING FIRE Straight Single Clapper Fire Department Connection (FDC) is a component of a fire protection system that provides a means for firefighters to connect their hoses to a building's fire suppression system.

The FDC is typically a vertical pipe that extends from the building's exterior and is equipped with a single clapper valve. This valve prevents water from flowing out of the FDC when it is not in use but allows water to flow into the building's sprinkler or standpipe system when the firefighters connect their hoses to the FDC.

The Straight Single Clapper FDC is named so because it has a straight pipe and a single clapper valve. Other types of FDCs include the Siamese FDC, which has two inlets, and the Wye FDC, which has two outlets.

The FDC is an important component of a building's fire protection system and is required by most building codes and fire safety regulations. It enables firefighters to quickly and easily connect their hoses to the building's sprinkler or standpipe system, allowing them to more effectively fight fires and protect property and lives.
