ASCO电磁阀在液路系统中用来实现液路的通断或液流方向的改变，它一般具有一个可以在线圈电磁力驱动下滑动的阀芯，阀芯在不同的位置时，电磁阀的通路也就不同。阀芯的工作位置有几个，该电磁阀就叫几位电磁阀：阀体上的接口，也就是电磁阀的通路数，有几个通路口，该电磁阀就叫几通电磁阀。电磁阀安装后，一般所有接口都应该是连接好了的，所谓工作位置指的是阀芯的位置。阀芯在线圈不通电时处在甲位置，在线圈通电时处在乙位置，阀芯在不同位置时，对各接口起到或接通或封闭的作用。电磁阀二位是指电磁阀的阀芯有两个不同的工作位置（开、关）。电磁阀二通、三通指电磁阀的阀体上有两个、三个通道口；比如二位二通电磁阀是一进一出（二个通道、***普通常见）二位三通电磁阀控制液体是一进二出（两出分别是一个常开一个常闭）；气动换向电磁阀是一进一出一排气；液压一进一出一回油。部分型号：SCG531B001MSSCG551B401MOSCG551A065SCG551A066SCG552A001SCG551A001MSSCG551A017MSSCG552A017MS238410-058-D272614-155-D238410-058-D238710-006-D238610-158-D238610-032-D238614-058-D238510-034-D272614-155-D272610-132-D238714-006-D238710-006-D272610-058-D238210-058-D064982-005-DEF8551A001MSEF8551A017MSEFG551H465EFG551H466EFG552G401MO8210G94HT8316G645700001457000103HT8316G64HT8344G80WSNF8327A1128320G1748210G009EF8210G201EF8262G212NFB327A0028344G0728223G0278263G205LT8316G066EF8320G174EF8320G1768320G184EF8320G1848320G186EFG551H401238610-058-D099257-006-DWT8551A001MSEF8551A001MSSCG551A2018551B401EF8344G370WSNF8327B112OFSF8263G206VNFG353A043SCG353A05152100001521000045210000552000380126000246056230034600137JBEF8320G174SCG553A017SCG551A41918900001NFB327A00252100008520000083550033535500333355003373550034143004886355003463550034735500338SCG551A005MSSCG551A017MSSCG551A018MSSCG551A001MSSCG551A002MS5420000112600008NFB370A047NF8327B112SCG531B001MSWSNF8551A421SCB344A074SC8344A074SCE370A008MSEFG551G401M08215***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)
