A fire butterfly valve, also known as a firefighting butterfly valve, is an essential component of a fire protection system. It is primarily used to control and regulate the flow of water or other extinguishing agents in case of a fire emergency.

The valve is designed with a disc that rotates ninety degrees within the pipe to either open or close the flow. Its unique butterfly-shaped disc allows for quick and efficient operation, reducing the response time during fire emergencies.

Fire butterfly valves are often installed in fire suppression systems, hydrants, and fire pumpsets.
