product performance
1. It is normally closed. In case of fire, the smoke (temperature) sensor sends an electrical signal (DC24V/DC220V) through the control center to energize the electromagnet in the actuator, and the valve automatically opens and outputs an opening electrical signal.
2. The valve can be opened manually.
3 Manual reset after valve action.
Product structure:
Main components: valve body, blade, shaft, bushing, temperature sensor, actuator, stainless steel spring plate, torsion spring, etc.
The middle frame is added in the W direction, and the maximum manufacturing size of the vane separation valve is 1200*800. The torsion of the torsion spring of the actuator can be adjusted in three steps to adjust the size of the 0WX H matched air duct, and the flange size is the same as that of the metal rectangular air duct in GB50234-2002.
