Product performance:

1. Normally open. When the air temperature in the pipeline reaches 70°C, the temperature sensor acts, and the valve automatically closes.

2. The valve can be opened and closed manually, and it will be reset manually after the valve moves.

3. The valve has six gears to manually adjust the opening of air volume. 4. The valve closing signal can be output.

Product structure:

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

The maximum manufacturing size of the valve: 1200*800WX H matches the size of the air duct, and the flange size is the same as that of the metal rectangular air duct in GB50234-2002.
