Round round fire valves for piping HVAC piping air dampers Smoke, smoke exhaust/ventilation
Normally, the damper is open, but in the event of a fire, the fuse plug will automatically close when the fuse reaches its fuse temperature of 70°C. Then we manually open the dampers to reset the system.
Normally, we need to close the valve manually, but when a fire breaks out and it reaches 70°C, it automatically closes and we can adjust the blade Angle between 0° and 90°. Rectangular or square dampers with rounded iron flanges are made of aluminum or galvanized steel or stainless steel. We also offer round fire valves.
Custom sizes and additional signal equipment requirements are welcome, if you have such questions, please feel free to contact us.
Fire dampers are designed with diverse structural features based on specific functions, encompassing smoke exhaust valves, smoke exhaust fire dampers, fire control valves, and dual smoke and fire control valves. The smoke exhaust valve, a guardian in high-rise and underground building smoke exhaust systems, performs core functions: it synchronizes with temperature (smoke) signals to activate the smoke exhaust fan or can be manually engaged to initiate the fan. It also sends signals indicating valve positions. The smoke exhaust fire damper, found in systems balancing smoke extraction with fire prevention, acts decisively by melting at exhaust temperatures above 280, shutting the valve and halting the fan. The fire-proof regulating valve, integrated into fire-resistant ventilation and air-conditioning pipelines, is engineered to seal at 70, signaling closure and fan cessation while allowing for seamless air volume adjustments. Similarly, the smoke and fire-proof regulating valve, catering to dual protection needs, is responsive to smoke and temperature signals, manually or automatically closing the valve and stopping the fan while adapting air volume through precise divisions.
