Performance:

1. It is normally closed. In case of fire, the smoke sensor sends an electrical signal (DC24v) through the control center, and the electromagnet in the mechanism is energized, so that the valve automatically opens and outputs an opening electrical signal.

2. The valve can be opened manually.

3. Manual reset after valve action.

Structure:

Main components: valve body, blade, shaft, bushing, actuator, etc. Maximum manufacturing size of valve: 800 x800

Matching actuator model: JPYF SDc-K-bWxH matching air duct size
