Fire control valve

Installed on the air supply and return pipes of the ventilation and air conditioning system, it is usually open. When the smoke temperature in the pipe reaches 70 degrees, it will be closed when the smoke temperature in the pipe reaches 70 degrees, and it can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time.

Product Details

Fire control valve
Material: carbon material, galvanized sheet
Installed on the air supply and return pipes of the ventilation and air conditioning system, it is usually open. When the smoke temperature in the pipe reaches 70 degrees, it will be closed when the smoke temperature in the pipe reaches 70 degrees, and it can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time.

Introduction:
Material: carbon material, galvanized sheet [1]
(1) The valve is normally open. When the airflow temperature reaches 70 ℃, the temperature sensor acts and the valve is closed;
(2) Manually adjust the opening degree of the blade within the range of 0 ° ~ 90 °;
(3) Manual shutdown or manual reset;
(4) The output valve closing signal can be interlocked with other fire prevention equipment.

Advantages:
1. Low air leakage and good air tightness.
2. Strong anti-corrosion performance and long service life.
3. The actuator is driven flexibly. Feedback and interlock signals are accurate.
Main functions and features
1. Manually open, manually reset and close.
2. It can output valve opening signal and interlock control signal.
The fire control valve is usually installed on the air duct of the ventilation and air conditioning system that needs to adjust the air volume, and is suitable for the air duct of horizontal or vertical airflow. Smoke fire control valve is usually installed in the need to adjust the air volume or need to use electric signal control valve closed ventilation and air conditioning system on the duct. Ducting for horizontal or vertical airflow.
Small fire control valve is usually installed in the ventilation area is small, compact space ventilation and air conditioning system on the duct, suitable for horizontal or vertical airflow duct

Indicators:
(1) input DC24V electrical signal, electromagnet action, the valve automatically closed.
(2)70 ℃ temperature sensor action, the valve automatically closed.
(3) Manual closing.
(4) Output shutdown signal or interlock control signal.
(5) Manually adjust the blade angle and adjust the air volume in fifth gear.
(6) Working voltage: DC24V 10℉,-15℉
(7) Working current: ≤ 0.3A.
(8) The temperature sensor is 70 ℃ fusible sheet. If 70 ℃ shape memory alloy temperature sensor is used, please indicate it when designing and ordering.
(9) Air leakage: in line with national standards (see inspection report).
(10) insulation resistance:> 20M fire resistance time> 90min
(11) Corrosion resistance and action reliability conform to the state.
