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. After the valve is actuated, it can be remotely reset by wire rope.

Structure:

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

Maximum manufacturing size of valve: 1250×800 matching actuator model: KPY SDc-YKWxH matching air duct size.
