電(dian)動蝶(die)閥(fa)分(fen)開(kai)關(guan)型和(he)調(tiao)節型(xing)兩(liang)種
電(dian)動蝶(die)閥(fa)分(fen)開(kai)關(guan)型和(he)調(tiao)節型(xing)兩(liang)種。電(dian)動蝶(die)閥(fa)是(shi)由電(dian)動(dong)執行(xing)器和(he)蝶(die)閥(fa)通過機(ji)械(xie)連(lian)接共(gong)同(tong)組成使(shi)用(yong)。配開(kai)關(guan)型電(dian)動執(zhi)行器(qi)的電動(dong)蝶(die)閥(fa)，直(zhi)接接通電源（AC220V或AC380V）通過正(zheng)、反(fan)轉來完成開(kai)關(guan)動作(zuo)。配調(tiao)節型(xing)電(dian)動(dong)執行器(qi)的蝶(die)閥(fa)以AC220V或AC380V電(dian)源作(zuo)為(wei)動(dong)力(li)，采(cai)用(yong)先進(jin)計(ji)算(suan)機(ji)單(dan)片(pian)及智(zhi)能控制軟件(jian)直(zhi)接接收計(ji)算(suan)機(ji)或(huo)工(gong)業(ye)儀(yi)表(biao)等(deng)輸出(chu)的標準(zhun)信(xin)號(hao)（4-20mA DC或(huo)1-5V DC）實現(xian)閥(fa)門(men)開(kai)度的智(zhi)能控制和(he)定位(wei)。
