2FRM.K
2通流量控制閥
規(guī)格6和10
作為插裝閥（"K"）
有集成單向閥
低啟動沖擊 特點；
1.控制閥有各種不同類型，它們的適用場合不同，因此，應(yīng)根據(jù)工藝生產(chǎn)過程的要求合理選擇控制閥類型。
2.氣動類控制閥分氣開和氣關(guān)兩類。氣開控制閥在故障狀態(tài)時關(guān)閉，氣關(guān)控制閥在故障狀態(tài)時打開?？刹捎靡恍┹o助設(shè)備組成保位閥或使控制閥自鎖，即故障時控制閥保持故障前的閥門開度
3.氣開和氣關(guān)的方式可通過正、反作用的執(zhí)行機(jī)構(gòu)類型和正體、反體閥的組合實現(xiàn)，在使用閥門定位器時，也可通過閥門定位器實現(xiàn)
4.各種控制閥結(jié)構(gòu)不同，各有特色。 從控制閥應(yīng)用看，發(fā)展方向如下：
a.小型執(zhí)行機(jī)構(gòu)：可降低成本，提高流通能力 ．
b.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
c.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
d.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，而且可降低成本。
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，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
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
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(bǔ)償被控對象非線性，將較少選用控制閥流量特性來補(bǔ)償被控對象非線性
5.閥內(nèi)件的材料隨溫度變化，因此，應(yīng)考慮不同溫度下熱膨脹造成的影響，也要考慮在高溫下耐壓等級的變化等，應(yīng)考慮材料的耐腐蝕性、抗疲勞性等性能。
