Target requirements for fire control valves:

Fire control valve data: carbon data, galvanized sheet

The device is installed on the supply and return air ducts of the ventilation and air dispatch system, usually in an open position. In the event of a fire, when the temperature of the smoke in the duct reaches 70 degrees, it is closed and can meet the requirements of smoke leakage and fire resistance for a certain period of time, achieving the effect of smoke isolation and fire prevention.

1. Input a DC24V electrical signal and activate the electromagnet to actively close the valve.

The 2.70 ℃ temperature sensor activates and the valve actively closes.

3. Manual closure.

4. Output closed signal or interlocking control signal.

5. Manually adjust the blade viewpoint and adjust the air volume in five levels.

6. Homework voltage: DC24V+10 ℅, -15 ℅

7. Homework current: ≤ 0.3A.

8. The temperature sensor is a 70 ℃ melting plate. If using a 70 ℃ shape memory alloy temperature sensor, please specify it during design and ordering.

9. Air leakage rate: in accordance with national standards (see inspection statement).

10. Insulation resistance:>20M, fire resistance time>90min
