  • product introduction:Material: galvanized steel plate Structure: mainly composed of valve body, blade, shaft, shaft sleeve, connecting rod, seal, temperature sensor, actuator and other parts; The flange is made of a common plate flange with a width of 35mm. Main technical parameters: temperature sensor action temperature: 70 ℃ Fire endurance: ≥ 1.5 hours Resistance coefficient at full opening: ≤ 0.5 Power supply: DC24V ± 10%, rated current ≤ 0.7A Function description: the valve is normally open. In case of fire, the control center sends a signal to input 24V DC power. The solenoid in the actuator is energized, and the valve automatically closes to cut off the smoke spreading along the air duct. After the valve acts, it can be manually reset. The valve can also be closed manually or the temperature sensor can be fused and closed when the temperature reaches 70 ℃. The valve has the function of manual six-speed air volume adjustment and outputs two groups of passive feedback signals.
