氣缸式調(diào)節(jié)閥（RPV6）
    ROPO新一代高性能氣動調(diào)節(jié)閥是根據(jù)德國*技術(shù)研制的新型直行程控制閥，是當前*水平的產(chǎn)品。采用的帶彈簧的雙作用氣缸式執(zhí)行機構(gòu)，具有很大的推力和很高的剛性強度，動作靈敏，定位精度高，響應(yīng)速度快。采用模塊化設(shè)計、裝配，現(xiàn)場維護極其方便。具有調(diào)節(jié)、切斷、切斷壓差大、泄漏量小等特點，是當前一代控制閥。
    ◇ 帶閥籠的雙導向單座閥，籠式套筒閥結(jié)構(gòu)緊湊體積小，動作靈敏部件少，性能穩(wěn)定易維護。
    ◇ 閥芯和閥桿為一體式，閥桿比傳統(tǒng)閥桿粗2-3倍，可承受高壓差并消除了閥芯脫落、閥桿
     彎曲斷裂的事故隱患。
    ◇ 氣缸經(jīng)硬質(zhì)陽極氧化處理入純凈的壓縮空氣，*腐蝕，使用壽命長。
    ◇ 閥門的關(guān)閉是借助于流體的壓力，彈簧反作用力和氣缸推力，具有抵抗非常高的流體壓差
     和關(guān)斷推力，使閥門關(guān)閉的更加嚴密。
    ◇ 同一規(guī)格閥門有多種CV值，只更換閥芯閥座就可實現(xiàn)。

ROPO this kind of super performance control valve is a series of products that introduce from them. According to different working conditions. Its features include simple structure, small size and light weight. It also enjoys advantages of small driving moment, good function of flow adjustment and airproof. The special designing and manufacturing processes effectively avoid the negative effects of temperature and cavitations of steam to the valve, thus extending the working life of the valve and ensuring safe operation. Thus, the compacted type series replaces the old products compley and is widely used automation fields of petroleum, chemical, metallurgy and other industries.
