Advantages a fire dampers, air leakage and low stainless steel dampers, airtight performance; 2, the electric current consumption is small open; 3, strong corrosion resistance and long service life; (made of stainless steel type) 4, the actuator drive flexible feedback interlock signal accurately. 1. normally open damper type smoke damper 2. normally closed smoke damper 3. Remote control type smoke damper (rope-controlled) 4. Automatic reset type smoke damper 2.3 remote-controlled row smoke dampers (rope-controlled) function as follows: 2.3.1 has a normally closed type smoke damper all the functions can be remote manually open 2.3.2, 2.3.3 manual reset closed rope controlling the distance standard 6m (. Long can be customized) 2.4 automatic reset type smoke damper functions as follows: 2.4.1 usually was normally closed when the fire broke out, by the control center DC24V power input, the valve automatically opens 2.4.2 pipeline when the temperature reaches 280 ℃. stainless steel damper effect, fuse action, the valve automatically closes. 2.4.3 can be manually turned on. After the 2.4.4 valve open, without manual reset stainless steel damper manufacturers, as long as the input DC24V power, the valve can be automatically reset to its original closed position (this temperature sensor function is not limited to action before such action to be replaced after a temperature sensor temperature sensor can still use this feature) 2.4.5 Output signal valve open, start and stop the stainless steel exhaust fan interlock control damper effect.. | stainless steel damper | Rui Xincheng air conditioning provided by the Texas Air Conditioning Equipment Co., Ltd.
