Product performance:

1. It is normally open. In case of fire, the smoke (temperature) sensor sends an electrical signal (DC24V) through the control center, and the electromagnet in the actuator is energized to automatically close the valve and output a closing electrical signal.

2. The valve can be closed manually or by the action of 280°C temperature sensor.

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*800WX H, which matches the size of the air duct, and the flange size is the same as that of the metal rectangular air duct in GB50234-2002.
