The need for safety devices is increasing day by day in a fast-growing technology era. Many heating appliances involve oil fuel or liquefied petroleum gas burning in furnaces providing heat to the working facilities and our homes with controlled fires and careful management. The risk of blazing fire escaping from furnaces will cause potential harm and hazardous to our lives and damages to our houses. Remote acting fire valve (RAF) safeguard against the fuel being fed into the fire and prevent the total destruction by fire. The automated fire safety valve utilizes the temperature control sensor governed to minimize the risk of fire. The RAF with cut off temperature 66 ℃ or 90 ℃ depends on the model, the flow rate of 395 liters/hour with 2m head approved by BS5410. This paper demonstrates the operation, calibration, function, and Reworks of Remote Acting Fire valve (RAF), manufactured and assembled in Tesla Technologies Private limited Pakistan. RAF is a safety device designated to cut off fuels supply to heating appliances that may have malfunctioned. Failure and Reworks of RAF are the problems need to be resolved. The proposed solution to the rework problems at Tesla Private limited would be beneficial to the company and customers.
