Five types of resiliently seated butterfly valves were tested under realistic shipboard fire conditions at the U.S. Coast Guard Fire and Safety Test Facility, Mobile, Alabama. These tests were intended to determine the effectiveness of resiliently seated butterfly valves as positive shutoff devices when exposed to realistic shipboard fire conditions. For comparison purposes, a metal seated valve 4 in gate valve was also tested. Five fires, each 500 sqft., were run for a period of approximately twenty-two minutes. Three valves 4 in, 6 in, 10 in were tested simultaneously except for test number four where only two valves were tested. For each valve the temperature of the wafer, the body, and the air temperature profile, one inch below the valve was recorded as well as the pressure at the inlet side.
