Main technical parameters
1. Air leakage (differential pressure 300pa): ≤ 700m3 / m2 h;
2. Control voltage: DC24V;
3. Contact capacity of microswitch: AC380V = 0.5A;
4. The positive force coefficient of full availability is less than 0.5.
Structure: main components: outer frame, panel, shaft and actuator.
Performance: it is normally closed at ordinary times. In case of fire alarm, the smoke detector sends an electrical signal (DC24V) through the control center. The electromagnet in the actuator is energized and the valve opens automatically. And output the opening electrical signal. The valve can be manually operated remotely
Open the valve and reset it manually from a long distance after the valve acts.
