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, action signal or reset signal feedback to the control center and start the equipment.

Structure:

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

Maximum manufacturing size of valve: 1250×800.

Model of supporting actuator: JPYF SDj-YKW×H size of supporting air duct
