Automatic fire dampers and smoke exhaust valves are indispensable guardians of safety, meticulously engineered to halt the treacherous spread of fire and smoke during emergencies. These critical devices, nestled within HVAC systems, spring into action, sealing off pathways when an alarm or heat detector sounds, thereby thwarting the spread from one building area to another. Compliance with building codes demands their presence, and diligent regular inspections assure their readiness. Meanwhile, smoke exhaust valves, the vigilant sentinels in ductwork, activate upon detecting smoke, efficiently channeling it away from escape routes and pivotal areas, ensuring the path to safety remains unhindered and firefighting efforts unobstructed. The synergy between these devices is paramount for occupant safety and effective fire containment. Their installation, maintenance, and testing are not just essential-they are lifesaving.
Fire dampers are versatile, each tailored for specific protective duties: 1. Smoke Exhaust Valves - Strategically positioned within high-rise and subterranean smoke exhaust systems, they coordinate with temperature and smoke signals to initiate the smoke exhaust fans simultaneously, or can be manually activated. 2. Smoke Exhaust Fire Dampers - Located within systems requiring both smoke extraction and fire prevention, they react at temperatures exceeding 280, shutting down to halt fan operation. 3. Fire-Proof Regulating Valves - Essential for fire-required HVAC systems, they respond at 70, ensuring complete valve closure and system shutdown while offering variable air volume modulation. 4. Smoke and Fire-Proof Regulating Valves - Integral to both smoke and fire-proof systems, these valves respond to smoke and heat signals, stop fans, and adjust air volume through precise, incremental changes.

Point of choice
1, the main control parameters of the fire valve are specifications.
2. Fire valve is suitable for ventilation and air conditioning system. In addition to the fire valve used in the kitchen exhaust system of public buildings, the working temperature is 150°C, and the working temperature of the fire valve in the general ventilation and air conditioning system is 70°C.
3, fire valve is suitable for ventilation, air conditioning or smoke exhaust system pipes.
4, when selecting the valve, pay attention to the function of the valve, such as normally open or normally closed, automatic closing, manual closing, manual reset, signal output, remote control and other requirements.
