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zui小 ．
e.簡單流路：流路簡單，流阻減小，不僅可使閥兩端壓損下降，而且可降成本。
f.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)計中不僅要密封問題，對摩擦和壽命等性能指標也必須重視 因此，近年來，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
g.降噪聲：采用多種方式降控制閥噪聲，例如，采用降噪套筒和閥芯，采用多級閥芯，采用降噪限流板，采用擴展器等
h.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，有利于降成本，通過換流通能力大的閥內(nèi)件，可擴展流通能力，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
i.在數(shù)字化信息化時代，將較多采用智能閥門定位器或通過數(shù)字控制器等實現(xiàn)非線性規(guī)律，補償被控對象非線性，將較少選用控制閥流量特性來補償被控對象非線性.
