意(yì)大利ATOS伺服(fú)比例閥(fá)專業(yè)代理(lǐ)比例伺服閥(fá)（簡稱比例閥）是由比例電(diàn)磁(cí)鐵(tiě)取(qǔ)代普通液(yè)壓閥(fá)的調節(jié)和(hé)控製(zhì)裝(zhuāng)置而構成的。它(tā)可(kě)以(yǐ)按給定的(dí)輸入電(diàn)壓(yā)或電(diàn)流信號連續地按比例地(dì)遠距(jù)離(lí)地(dì)控製(zhì)流體的(dí)方(fāng)向(xiàng)，壓(yā)力(lì)和(hé)流量(liáng)。 　　采用電液(yè)比(bǐ)例控(kòng)製閥提高了(liǎo)係統(tǒng)的自(zì)動(dòng)化程度(dù)和(hé)精度，又簡(jiǎn)化(huà)了係統。 　　比例閥(fá)的(dí)工作雖用伺(sì)服閥可完成，但(dàn)後(hòu)者精度(dù)高，價格(gé)貴，對油液清潔度(dù)要求更(gēng)高(gāo)。比例閥主(zhǔ)要結(jié)構(gòu)與(yǔ)普(pǔ)通閥差別(bié)不大(dà)，隻(zhī)是比(bǐ)例閥(fá)均由比例電磁鐵驅(qū)動（一(yī)種(zhǒng)電(diàn)—機(jī)械轉(zhuǎn)換(huàn)器）。 　　比(bǐ)例閥分為(wéi)：比(bǐ)例(lì)壓(yā)力(lì)閥，比例流量閥(fá)和比(bǐ)例方(fāng)向閥 　　
電液比例伺(sì)服閥又(yòu)叫(jiào)電液(yè)伺(sì)服(fú)比例閥，來(lái)源於(yú)比例技術(shù)與伺(sì)服技(jì)術的結合，一種是(shì)采用(yòng)比例(lì)電磁鐵作為電-機(jī)轉換器(qì)，將(jiāng)傳統電液比例(lì)閥的(dí)功(gōng)率(shuài)滑閥(fá)改(gǎi)進(jìn)成伺服閥(fá)的(dí)閥芯(xīn)，閥(fá)套結構；一種(zhǒng)是將(jiāng)電液伺服(fú)閥(fá)的意(yì)大利ATOS伺服比例(lì)閥(fá)專(zhuān)業代理(lǐ)滑(huá)閥(fá)的(dí)閥(fá)套(tào)結構(gòu)去掉，機械反(fǎn)饋(kuì)改(gǎi)為電(diàn)反饋(kuì)。伺服(fú)比例閥
