     FESTO比例調(diào)節(jié)閥功效和封閉密封特性，在大中口徑、中低壓力的應用范疇，電動球閥是主導的閥門情勢。電動球閥處于完整開啟地位時，蝶板厚度是介質(zhì)流經(jīng)閥體時*的阻力，因此通過該閥門所發(fā)生的壓力降很小，故具有較好的流量把持特征。電動球閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。 采取金屬密封的閥門一般比彈性密封的閥門壽命長，但很難做到完整密封。金屬密封能適應較高的 工作溫度，彈性密封則具有受溫度限制的缺 點。 假如請求電動球閥作為流量把持使用，重要的是準確選擇閥門的尺寸和類型。電動球閥的構(gòu)造原理尤其合適制造大口徑閥門。電動球閥不僅在石油、煤氣、化工、水處置等一般產(chǎn)業(yè)上得到普遍運用，而且還利用于熱電站的冷卻水體系。
    FESTO比例調(diào)節(jié)閥自力式壓力控制閥）無需外加能源，利用被調(diào)介質(zhì)自身能量為動力源，引入執(zhí)行機構(gòu)控制閥芯位置，改彎兩端的壓差和流量，使閥前（或閥后）壓力穩(wěn)定。具有動作靈敏，密封性好，壓力設定點波動力小等優(yōu)點，自力式壓力控制閥廣泛應用于氣體、液體及蒸汽介質(zhì)減壓穩(wěn)壓或泄壓穩(wěn)壓的自動控制。
