2. Fire-safe valve is suitable for ventilation and air-conditioning systems. The operating temperature of fire-safe valve in kitchen exhaust system of public buildings is 150 degrees Celsius. Usually, the operating temperature of fire-safe valve in ventilation and air-conditioning systems is 70 degrees Celsius.

3. Fire-safe valve is suitable for pipelines of ventilation, air-conditioning and exhaust systems.

4. Pay attention to the functions of sanitary valves when making choices. Automatic closing and opening, manual closing and opening, manual reset, signal output, remote control and other requirements should be paid attention to.

5. If the valve is associated with the fan, dual micro switch device should be used.

6. The blade of the valve body should be steel plate, with a thickness of 2~6mm. The valve body is made of non-combustible materials and the rotating parts should be corrosion-resistant metal materials with flexible rotation. The thickness of the external shell of the valve shouldn’t be less than 2mm.
