德國費斯托FESTO電磁閥產品簡介：

FESTO電(dian)磁閥的用途電(dian)磁閥用于液體和氣體管路的開關(guan)(guan)控(kong)(kong)制(zhi)(zhi)，是兩(liang)位DO控(kong)(kong)制(zhi)(zhi)。一(yi)般用(yong)于(yu)小(xiao)型管(guan)(guan)道(dao)的控(kong)(kong)制(zhi)(zhi)。電(dian)(dian)(dian)(dian)(dian)動(dong)閥(fa)(fa)用(yong)于(yu)液體、氣體和風系統管(guan)(guan)道(dao)介質(zhi)流量(liang)的模擬量(liang)調(diao)節(jie)，是AI控(kong)(kong)制(zhi)(zhi)。在大(da)型閥(fa)(fa)門和風系統的控(kong)(kong)制(zhi)(zhi)中也可(ke)以用(yong)電(dian)(dian)(dian)(dian)(dian)動(dong)閥(fa)(fa)做(zuo)兩(liang)位開關(guan)(guan)控(kong)(kong)制(zhi)(zhi)。電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)只(zhi)(zhi)能用(yong)作開關(guan)(guan)量(liang)，是DO控(kong)(kong)制(zhi)(zhi)，只(zhi)(zhi)能用(yong)于(yu)小(xiao)管(guan)(guan)道(dao)控(kong)(kong)制(zhi)(zhi)，常見(jian)于(yu)DN50及(ji)以下管(guan)(guan)道(dao)，往上就(jiu)很(hen)少了。電(dian)(dian)(dian)(dian)(dian)動(dong)閥(fa)(fa)可(ke)以有AI反饋信號，可(ke)以由DO或(huo)(huo)AO控(kong)(kong)制(zhi)(zhi)，比較見(jian)于(yu)大(da)管(guan)(guan)道(dao)和風閥(fa)(fa)等(deng)。1.開關(guan)(guan)形式電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)通過線圈驅(qu)動(dong)，只(zhi)(zhi)能開或(huo)(huo)關(guan)(guan)，開關(guan)(guan)時(shi)(shi)動(dong)作時(shi)(shi)間短(duan)。電(dian)(dian)(dian)(dian)(dian)動(dong)閥(fa)(fa)的驅(qu)動(dong)一(yi)般是用(yong)電(dian)(dian)(dian)(dian)(dian)機，開或(huo)(huo)關(guan)(guan)動(dong)作完成需要一(yi)定的時(shi)(shi)間模擬量(liang)的，可(ke)以做(zuo)調(diao)節(jie)。2.工(gong)作性質(zhi)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)一(yi)般流通系數很(hen)小(xiao)，而(er)且工(gong)作壓力差很(hen)小(xiao)。比如(ru)一(yi)般25口徑的電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)流通系數比15口徑的電(dian)(dian)(dian)(dian)(dian)動(dong)球閥(fa)(fa)小(xiao)很(hen)多

FESTO電磁(ci)閥隔磁(ci)套管內(nei)的鐵芯完成，不(bu)存在動(dong)密封(feng)，所以外(wai)漏易堵絕。電動閥力矩控(kong)制不易，容易產生內(nei)漏(lou)，甚至拉斷閥桿(gan)頭部；電(dian)磁閥的結構型式容易控(kong)制內(nei)泄漏(lou)，直至降為(wei)零。所以，電(dian)磁閥使用特別(bie)安全，尤其適用于腐蝕性、有毒或(huo)高低溫(wen)的介(jie)質。
