Marine Pneumatic Fire Damper

1. Features
The fire damper should normal open on getting compressed air&electric power, and should be close on loss of compressed air or electric power. Pneumatic operating pressure is 0.5-0.8MPa;
If the temperature of air in damper duct exceeds 70±3℃, the fusible link if fire damper will be broken and the change valve will cut off the compressed air source to close the fire damper;
On/off status of control electric source for solenoid change valve should be controlled locally or remotely, thus open/close the fire damper;
Manual change valve can be controlled by handle dragline, and the fire damper can close locally or remotely;
on/off signal output when the fire damper is on/off.
