1、70℃防火閥用在空調送風、通風系統管道上；平時常開，發生火災時關閉，聯鎖風機，使風機關閉；2、280℃防火閥用在排煙系統管道上，平時常開，發生火災時排煙，當煙氣溫度達到280度時，防火閥關閉，聯鎖風機關閉；3、280℃防火閥應為常開，又叫高溫防火閥，一般推薦不銹鋼通風管安裝在有高溫環境的通風管道中，當溫度到達280℃后易熔合金熔化，閥門關閉，同時可以用24V電信號控制。如果說是280排煙防火閥應為常閉，不銹鋼通風管安裝在排煙(yan)(yan)管道中(zhong)發生(sheng)火(huo)災時控制中(zhong)心(xin)給出電信(xin)號使其打開排煙(yan)(yan)，當溫度到達280時易熔(rong)合金熔(rong)化(hua)閥(fa)門關閉(bi)，是(shi)一種二次動作(zuo)的閥(fa)門。
