隨著國內(nèi)工業(yè)的快速發(fā)展，直接促使燃?xì)鉁p壓閥的普遍運(yùn)用，尤其是在治金行業(yè)還有就是石油化工等領(lǐng)域的使用，尤其是燃?xì)獗壤y穩(wěn)定的性能還有質(zhì)量的可靠性在行業(yè)競爭中顯得越來越重要了。與同規(guī)格的伺服閥相比，比例閥的成本大約是其50%。然而，伺服閥依然應(yīng)用在具有精密位置控制和速度控制的場合，諸如燃燒機(jī)、工業(yè)工程等。比例閥可用于流量和壓力控制，但是大多數(shù)情況下還是作為方向控制閥。盡管比例方向閥的設(shè)計會因不同廠商而已，但它們基本上都是完成同樣一種功能：控制燃?xì)飧谆蝰R達(dá)的方向和速度。通過使用反饋裝置諸如線性位移傳感器或者旋轉(zhuǎn)編碼器，執(zhí)行器的位置可以被精確控制。
