美国ASCO阿斯卡电磁阀ASCO直动式电磁阀一般为单电控（即单线圈），两位五通电磁阀一般为双电控（即双线圈）。线圈电压等级一般采用DC24V、AC220V等。两位三通电磁阀分为常闭型和常开型两种，常闭型指线圈没通电时气路是断的，常开型指线圈没通电时气路是通的。常闭型两位三通电磁阀动作原理：给线圈通电，气路接通，线圈一旦断电，气路就会断开，这相当于“点动”。常开型两位三通单电控电磁阀动作原理：给线圈通电，气路断开，线圈一旦断电，气路就会接通，这也是“点动”。两位五通双电控电磁阀动作原理：给正动作线圈通电，则正动作气路接通（正动作出气孔有气），即使给正动作线圈断电后正动作气路仍然是接通的，将会一直维持到给***作线圈通电为止。给***作线圈通电，则***作气路接通（***作出气孔有气），即使给***作线圈断电后***作气路仍然是接通的，将会一直维持到给正动作线圈通电为止。这相当于“自锁”。基于两位五通双电控电磁阀的这种特性，在设计机电控制回路或编制PLC程序的时候，可以让电磁阀线圈动作1~2秒就可以了，这样可以保护电磁阀线圈不容易损坏。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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)
