Performance:

1. It is normally closed. In case of fire, the smoke (temperature) sensor sends an electrical signal (DC24V) through the control center, and the electromagnet in the mechanism is energized, so that the valve automatically opens and outputs an opening electrical signal.

2. The valve can be opened manually.

3. Manual reset after valve action.

Structure:

Main components: valve body, blade, shaft, bushing, temperature sensor, actuator, stainless steel spring plate, etc.

W direction with middle frame, the maximum manufacturing size of the vane separation valve: 1250×800 actuator, torsion spring and torsion can be adjusted in three gears. Supporting actuator model: JPYFSDC-K.

W ×H matches the size of air duct, and the flange size is the same as the flange of metal rectangular air duct in GB50234-2002.
