Performance:

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

2. After the valve action, the DC motor is driven to reset.

3. The valve can be manually opened and reset.

4. The action signal or reset signal is fed back to the control center and the interlocking equipment is started.

Structure:

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

Maximum manufacturing size of valve: 1250×800. Model of supporting actuator: JPYF SDj-YK.

WW ×H, according to the size of air duct, the flange size is the same as the flange of metal rectangular air duct in GB50234-2002.
