比例閥通常包括兩個器件—一個導(dǎo)向控制和一個閥單元。導(dǎo)向控制由兩個2/2通路導(dǎo)向閥或一個比例電磁線圈（solenoid）組成，還包括用于評估的電子線路。閥單元只包含集成的氣動功能。一個直流電壓或電流(例如0~10V電壓或0~20mA電流)作用于控制塊連接件。電壓或電流然后對應(yīng)于一個特定的被控壓力。在工作端口的實際壓力由集成的壓力傳感器測量，然后發(fā)送到評估電子線路，后者對實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“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，例如除“打開”或“關(guān)閉”等終點位置外，中間位置如“稍微打開”是可能的。用于切換工作位置的執(zhí)行器件是一個比例電磁線圈，當(dāng)電磁線圈被電子線路激勵時，線圈電壓會隨之改變，控制活塞的位置將按照此變化的電磁場強(qiáng)度而變化。作為其結(jié)果，借助于控制活塞的作用，每個空氣通路同時會有不同程度的打開或關(guān)閉。這不僅啟動氣缸移動方向的開環(huán)或閉環(huán)控制，還對氣缸的移動速度進(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。</p><div

對夾式蝶閥是用雙頭螺栓將閥門連接在兩管道法蘭之間，法蘭式蝶閥是閥門上帶有法蘭，用螺栓將閥門上兩端法蘭連接在管道法蘭上。球閥球閥是由旋塞閥演變而來。它具有相同的旋轉(zhuǎn)90度提動作，不同的是旋塞體是球體，有圓形通孔或通道通過其軸線。球面和通道口的比例應(yīng)該是這樣的，即當(dāng)球旋轉(zhuǎn)90度時，在進(jìn)、出口處應(yīng)全部呈現(xiàn)球面，從而截斷流動。球閥只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動力矩就能關(guān)閉嚴(yán)密。完全平等的閥體內(nèi)腔為介質(zhì)提供了阻力很小、直通的流道。通常認(rèn)為球閥**適宜直接做開閉使用，但近來的發(fā)展已將球閥設(shè)計成使它具有節(jié)流和控制流量之用。球閥的主要特點是本身結(jié)構(gòu)緊湊，易于操作和維修，適用于水、溶劑、酸和天然氣等一般工作介質(zhì)，而且還適用于工作條件惡劣的介質(zhì)，如氧氣、過氧化氫、甲烷和乙烯等。球閥閥體可以是整體的，也可以是組合式的。按防止介質(zhì)倒流選用閥門這種類型的閥門的作用是只允許介質(zhì)向一個方向流動，而且阻止方向流動。通常這種閥門是自動工作的，在一個方向流動的流體壓力作用下，閥瓣打開；流體反方向流動時，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動。其中止回閥就屬于這種類型的閥門，它包括旋啟式止回閥和升降式止回閥。</p><div
