Flammable storage tank fuse valve – closes automatically when the ambient temperature during a fire exceeds the set value; no power or gas supply required for operation

Thread Content

The design featuring a fuse-fired fire shut-off valve is intended to automatically cut off the piping systems carrying flammable substances or liquids, solvents, alcohol, toxic liquids, or any other potentially hazardous media when the ambient temperature reaches a set value. Once a fire breaks out, these valves will automatically stop the supply of flammable substances or liquids, solvents, alcohol, toxic liquids, or any other potentially hazardous materials, thereby reducing or eliminating the damage caused by the fire. In the event of a fire, the fuse of the fire shut-off valve disconnects automatically when it reaches a preset value, thereby activating the actuator at the top of the valve; as a result, the valve changes from an open state to a closed state, or from a closed state to an open state. Fire isolation valves come with different temperature settings, which can be chosen freely based on the specific conditions of a project. Generally, the set temperature for fire isolation valves should be 30°C higher than the ambient temperature. It is an ideal choice for the inlet and outlet systems of flammable storage tanks. Additionally, during use, the fire isolation valve can be reused by simply replacing the blown fuse online, thereby reducing operating costs.
