The main material: carbon steel, galvanized steel, stainless steel. 1. Purpose (1) in a normally closed valve usually electric multi-leaf delivery outlet, fire manually or automatically open when the temperature reaches 280 ℃ Lu'an airflow pressure delivery outlet, temperature sensor operation, the valve is closed; (2) DC24V power passing through the valve can be closed; (electric type smoke damper) (3) or manual reset manually shut down; (4) closed DC24V electric reset; (automatic type smoke damper for manual operation inconvenient places ) (4) Output valve closure signal can be interlocked with other fire-fighting equipment. Advantages: 1, low air leakage, airtight performance 2, the electric current consumption small open fire products. Our company is specialized in the production enterprises, the main products are fire dampers, exhaust valve electric pressure delivery outlet, smoke dampers,. temperature exhaust fan and other products. Exhaust valves are suitable: exhaust valve is usually installed in the exhaust duct system, usually normally closed, smoke detector send out alarm signals in case of fire, the control center to turn on the electric signal on the solenoid valve to open the valve quickly, too Keren quickly open the valves manually smoke. Performance: · Telecommunications No. DC24V ± 2.4V open the valve. ? Manual allows the valve to open, manual reset. · After the operation of the valve opening signal output. · According to user requirements can be interlocked with other equipment.
