　德國(guó)FESTO老虎閥用于液體和氣體管路的開(kāi)關(guān)控制，是兩位DO控制。一般用于小型管道的控制。電動(dòng)閥用于液體、氣體和風(fēng)系統(tǒng)管道介質(zhì)流量的模擬量調(diào)節(jié)，是AI控制。在大型閥門(mén)和風(fēng)系統(tǒng)的控制中也可以用電動(dòng)閥做兩位開(kāi)關(guān)控制。電磁閥只能用作開(kāi)關(guān)量，是DO控制，只能用于小管道控制，常見(jiàn)于DN50及以下管道，往上就很少了。電動(dòng)閥可以有AI反饋信號(hào)，可以由DO或AO控制，比較見(jiàn)于大管道和風(fēng)閥等。1.開(kāi)關(guān)形式電磁閥通過(guò)線圈驅(qū)動(dòng)，只能開(kāi)或關(guān)，開(kāi)關(guān)時(shí)動(dòng)作時(shí)間短。電動(dòng)閥的驅(qū)動(dòng)一般是用電機(jī)，開(kāi)或關(guān)動(dòng)作完成需要一定的時(shí)間模擬量的，可以做調(diào)節(jié)。2.工作性質(zhì)電磁閥一般流通系數(shù)很小，而且工作壓力差很小。比如一般25口徑的電磁閥流通系數(shù)比15口徑的電動(dòng)球閥小很多

德國(guó)FESTO老虎閥隔磁套管內(nèi)的鐵芯完成，不存在動(dòng)密封，所以外漏易堵絕。電動(dòng)閥力矩控制不易，容易產(chǎn)生內(nèi)漏，甚至拉斷閥桿頭部；電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏，直至降為零。所以，電磁閥使用特別安全，尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。
