小型執(zhí)行機(jī)構(gòu):可降低成本，提高流通能力 .
套筒導(dǎo)向:采用套筒導(dǎo)向，有利于對中，有利于降低摩擦，有利于降噪，有利于流量特性的互換
平衡式閥芯:為降低執(zhí)行機(jī)構(gòu)推力或推力矩，采用平衡式閥芯是重要的，它對系統(tǒng)的動態(tài)性能也有改善

一體化閥芯和閥座:為克服雙座閥密封性差的缺點，采用相同材質(zhì)的一體化閥芯和閥座組成閥內(nèi)件，將泄漏量和不平衡力同時減到小 .
簡單流路:流路簡單，流阻減小，不僅可使閥兩端壓損下降，而且可降低成本。
密封和摩擦:密封性能和摩擦性能是矛盾的兩方面，控制閥設(shè)計中不僅要解決密封問題，對摩擦和壽命等性能指標(biāo)也必須重視 因此，填料函和填料結(jié)構(gòu)的研究得到重視，旋轉(zhuǎn)型控制閥得到較廣泛應(yīng)用
降低噪聲:采用多種方式降低控制閥噪聲，例如，采用降噪套筒和閥芯，采用多級閥芯，采用降噪限流板，采用擴(kuò)展器等
采用與管道同直徑的控制閥和限制流通能力的閥內(nèi)件:利于降低閥入口壓力和出口流體流速，不需安裝異徑管等附加管件，有利于降低成本，通過更換流通能力大的閥內(nèi)件，可擴(kuò)展流通能力，通過選用限制流通能力閥內(nèi)件可糾正計算口徑過大的錯誤
