Customization air valve fire smoke manual and motorised damper actuator rated volume control dampers

Scope of application
Installed on the ducts of the ventilation and air-conditioning system with smoke and fire prevention requirements, it is usually open, and can be automatically closed when a fire occurs. When gas extinguishing is implemented, it can be automatically reset {open} to remove toxic gases. The valve is especially suitable for high-altitude, hidden places and systems for both exhaust air conditioning and ventilation in some important projects such as tall buildings, public buildings, and underground buildings.

Performance characteristics
1. Normally open, it will be closed automatically according to the signal (DC24V). or the valve can be closed manually or the medium temperature reaches 70 degrees.
2. The micro switch outputs the valve closing signal, and the parallel lock ventilation air-conditioning fan stops.
3. When the valve needs to be reopened, just input the electrical signal to {reset time about 20 seconds}, and the interlocking ventilation air-conditioning fan can be restarted.
4. The ventilation adjustment device can make the valve blades have difterent angles to adjust the air volume.

Scope of application
It is installed on the air duct of the ventilation and air-conditioning system with fire protection device. It is usually open, and the valve is closed when the temperature is 70 degrees. Installed on the smoke exhaust system, it is closed at 280 degrees.

Performance characteristics
1.The temperature fuse is working and the valve is closed.
2.The valve blades can adjust the air volume between 0-90 degrees.
3.A valve closing signal device can be set, which can be linked with the fire control center to control the stop of ventilation, air conditioning or exhaust fan.
4. If you need to set a valve closing signal device, please specily when ordering.


 

Scope of application
Installed on the pipe of the smoke exhaust system or the entrance of the exhaust fan, normally closed.

Performance characteristics
1. It is opened by electrical signal or manual operation, closed at 280 degrees, and reset manually.
2. Microswitch output signal and fire center interlocking exhaust fan start, and the air conditioner stops.
3. When the flue gas temperature exceeds 280 degrees, the valve is closed and the exhaust fan stops.
4. TY.HP .PFHF .WSDC280 is equipped with DC.S type long-distance automatic and manual device.

Scope of application
Installd on the pipe of the smoke exhaust system normally closed, start automatically or manually, reset manually. It can also be installed at the decorated smoke outlet.

Performance characteristics
1. Open the valve according to the fire signal or manual operation.
2. Output valve opening signal to interlock with related equipment.
3. TY.HP PYF .WSDC.K is configured to open and close the device remotely.
