70 ℃ fire control valve apply to have the ventilation and air conditioning system, fire safety requirements, when disaster occurs, damper specification, the temperature fuse in the fuse fusible ring 70 degrees. The valve is closed, fire dampers standards for the operation of fire dampers and smoke exhaust system fuses at 280 degrees. The valve is closed, exhaust system for the operation of fire dampers fuse at 280 degrees. Valve closed, cutting off the fire and smoke spread along the duct channel, the valve blade can be adjusted in the range of 0-90 degrees. Function (1) temperature of 70 degrees fuse action, the valve closes. (2) manually turned on or reset. (3) to manually change the opening angle of the blades. (4) According to the system requirements, increasing numbers of telecommunications equipment operation and fire interlock system or other systems. PSK-02SFD multi-leaf smoke / outlet Features: usually normally closed, electric, manual opening. Output Enable signal. Manual reset closed. 280 ℃ temperature sensor operation, Baotou damper valve is closed again. Using a thin-shaped bodies, fire dampers production, reduce operating box size, increase the effective area of ??the ventilation exhaust damper Advantages 1, low air leakage, airtight performance; 2, the electric current consumption small open; 3, anti-corrosion performance, long life; (made of stainless steel type) 4, Actuated flexible, feedback, interlock signal accurate.
