Air leakage rate (at differential pressure 300Pa): 700m³/m²·h
Control voltage: DC24V
Resistance coefficient when the valve is fully open: ＜0.5
Valve fire resistance rating: 1.5h
Action time: 20 seconds
Main components: valve body, valve blade, shaft, shaft bush, fusible link, actuator.
All valve flanges adopt TDF flange with a flange width of 30mm.
Valve body plate thickness: 2.0mm, valve blade plate thickness: 2.0mm.
Length of rectangular valve body: L=250mm.
Performance
The valve is normally closed under normal conditions.
In case of fire, the smoke detector sends DC24V electrical signals through the control center. The electromagnet inside the actuator is energized to operate, the valve opens automatically and outputs an opening signal.
After valve action, reset is driven by DC motor. The valve can be manually opened and manually reset.
