Performance:

1. It is normally open at ordinary times. 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 an electrical signal for closing.

2. The valve can be closed manually or the temperature sensor at 280℃ can be closed.

3. Manual reset after valve action.

Structure:

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

W direction with middle frame, the maximum manufacturing size of the vane separation valve: 1250×800 The torsion of the torsion spring of the actuator can be adjusted in three gears.

Model of supporting actuator: JPF HF WSDC-K.

W ×H matches the size of air duct, and the flange size is the same as the flange of metal rectangular air duct in GB50234-2002.
