Product Description
Product Description
 
Automatic fire dampers and smoke exhaust valves are indispensable safety components integrated into buildings to thwart the spread of perilous fire and smoke during unforeseen emergencies. These cutting-edge fire dampers are engineered to activate and seal upon receiving signals from fire alarms or heat detectors, strategically installed within HVAC ducts to halt fire and smoke from migrating between building sections. Complying with stringent building codes and regulations, these dampers undergo rigorous testing and inspections to guarantee optimal performance. Conversely, smoke exhaust valves are crucial in expelling smoke during fires, adeptly installed in ducts and triggered by an advanced control system that monitors smoke concentrations. These valves are pivotal in preventing smoke accumulation, ensuring clear escape paths and aiding firefighting endeavors. Both automatic fire dampers and smoke exhaust valves are paramount in safeguarding occupants and mitigating fire and smoke risks within structures, demanding meticulous installation, maintenance, and routine testing to assure their flawless operation when urgently required.
 
 
 
Product Parameters
 
Fire dampers are ingeniously categorized by their functional structures: smoke exhaust valves, smoke exhaust fire dampers, fire control valves, and smoke and fire control valves, each serving unique purposes. Smoke exhaust valves, crucial for high-rise and subterranean buildings, synchronize with temperature (smoke) signals, activating the smoke exhaust fan upon manual or automatic valve operation, while transmitting valve status signals. Smoke exhaust fire dampers, designed for ducts adhering to smoke and fire prevention protocols, automatically close and halt exhaust fans if temperatures surpass 280°C. Fire-proof regulating valves, tailored for ventilation and air-conditioning systems demanding fire resistance, seal the valve at 70°C, stopping the fan and offering stepless air volume regulation. Smoke and fire-proof regulating valves, also for ventilation systems, respond to smoke (temperature) signals by sealing the valve and fan, while manual closure and a 70°C temperature fuse provide additional safeguards, with precise air volume adjustments across a 90° range in five equal increments.
