Product Description
Main Technical Parameters
Air leakage rate (under differential pressure of 300Pa): ≤700m³/m²·h
Microswitch contact capacity: AC380V <0.5A
Control voltage: DC24V
Resistance coefficient at fully open state: <0.5

Structure
Main components: valve body, valve blade, shaft, shaft bush and actuator.
Thickness of smoke exhaust outlet: L=200mm.

Performance
It is installed in the smoke exhaust system and kept normally closed in normal conditions.
In case of fire, the smoke detector sends DC24V electrical signal via the control center. The electromagnet inside the actuator is energized to actuate, the valve opens automatically and outputs an opening electrical signal to interlock and start the smoke exhaust fan.
The valve can be manually opened remotely by steel wire rope, and can be reset and closed through the wall-mounted actuator.
Steel wire rope available in lengths: 6m, 9m and 12m.
