體化閥芯和閥座：為克服雙座閥密封性差的缺點(diǎn)，采用相同材質(zhì)的體化閥芯和閥座組成閥內件，將泄漏量和不平衡力同時(shí)減到zui小 ．
e.簡(jiǎn)單流路：流路簡(jiǎn)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，控制閥設計中不僅要密封問(wèn)題，對摩擦和壽命等性能指標也必須重視 因此，近年來(lái)，填料函和填料結構的研究得到重視，旋轉型控制閥得到較廣泛應用
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(guò)換流通能力大的閥內件，可擴展流通能力，通過(guò)選用限制流通能力閥內件可糾正計算口徑過(guò)大的錯誤
i.在數字化信息化時(shí)代，將較多采用智能閥門(mén)定位器或通過(guò)數字控制器等實(shí)現非線(xiàn)性規律，補償被控對象非線(xiàn)性，將較少選用控制閥流量特性來(lái)補償被控對象非線(xiàn)性.
