ZXMI/ZDLMI Low Noise Cage Control Valve ZXMI/ZDLMI低噪音套筒控制閥采用套筒上打小孔或外套幾層多層小孔套筒，抗氣蝕、抗沖刷、以降低噪音和振動。 ZXMI/ZDLMI Low noise cage Control Valves are designed with pressure balanced type trim.It has features with dynamic stability,high pressure drop,low noise.Low noise cage control valves can be divided into following types:pneumatic type,electro-motion type and manual operation type.
內部類型（Trim Type） 1、三級減壓 適用于壓差小于5.5MPa的工況，噪音小于80dB(A)。 2、二級減壓 適用于壓差小于3.5MPa的工況，噪音小于80dB(A)。 標準規格(Standard specifications) 形式Type | 低噪音套筒控制閥Low Noise Cage Control Valve | 公稱通徑Body Size | DN20-DN450(3/4~18) | 公稱壓力Body Ratings | PN16,25,40,64,100;ANSI Class 150,300,600 | 閥體及閥蓋材質 Body&Bonnet Material | WCB,CF8,CF8M,CF3,CF3M,WC1,WC6,WC9,LCB,LCC,LC3,哈氏C… | 填料Packing | V型聚四氟乙稀 V-PTEE/柔性石墨 Flexible graphite | 墊圈Gasket | GRAP+304,GRAP+316,PTEE | 連接方式Connections | 法蘭型（RF、MFM）Flange type(RF,MFM)/焊接型（SW、BW）Welding type(SW,BW) | 涂層Painting Color | 棕色漆Brown painting/不銹鋼閥體可不涂漆No painting on stainless steel valve body | 執行機構Actuator | 氣動、電動、手動Pneumatic type,electro-motion type and manual operation typ | 閥蓋類型Bonnet Type | 標準型、波紋管密封型、低溫型、散熱型 Standard type,bellow seal type,low-temperature type,Fin-Extension type |
注：以上只是標準組合，根據工況條件，本表以外的規格也是可能的。 Note:the above is just a standard combination,according to the working conditions,other specifications are also possible.
