比例閥通常包括兩個(gè)器件—一個(gè)導(dǎo)向控制和一個(gè)閥單元。導(dǎo)向控制由兩個(gè)2/2通路導(dǎo)向閥或一個(gè)比例電磁線圈（solenoid）組成，還包括用于評(píng)估的電子線路。閥單元只包含集成的氣動(dòng)功能。一個(gè)直流電壓或電流(例如0~10V電壓或0~20mA電流)作用于控制塊連接件。電壓或電流然后對(duì)應(yīng)于一個(gè)特定的被控壓力。在工作端口的實(shí)際壓力由集成的壓力傳感器測(cè)量，然后發(fā)送到評(píng)估電子線路，后者對(duì)實(shí)際壓力和期望的壓力進(jìn)行比較。電子線路單元隨即根據(jù)壓力偏差依次切換導(dǎo)向閥和主閥的操作位置，一直到獲得期望的壓力。對(duì)“標(biāo)準(zhǔn)”的方向控制閥而言，只能有單一的切換位置，但比例方向控制閥還允許有中間位置。這就是說(shuō)，例如除“打開”或“關(guān)閉”等終點(diǎn)位置外，中間位置如“稍微打開”是可能的。用于切換工作位置的執(zhí)行器件是一個(gè)比例電磁線圈，當(dāng)電磁線圈被電子線路激勵(lì)時(shí)，線圈電壓會(huì)隨之改變，控制活塞的位置將按照此變化的電磁場(chǎng)強(qiáng)度而變化。作為其結(jié)果，借助于控制活塞的作用，每個(gè)空氣通路同時(shí)會(huì)有不同程度的打開或關(guān)閉。這不僅啟動(dòng)氣缸移動(dòng)方向的開環(huán)或閉環(huán)控制，還對(duì)氣缸的移動(dòng)速度進(jìn)行控制。因此，可以認(rèn)為這種閥起到節(jié)流的功能，在切換頻率約為100Hz時(shí)。</p><div
