ASCO电磁阀，二位四通电磁阀

ASCO电磁阀，二位四通电磁阀当主阀阀杯上的压力减少到一定值时，衔铁带动主阀阀杯，并利用压差而使主阀阀杯开启，介质流通。线圈断电后，电磁力消失，衔铁因自重下落复位。51800021 K302116 EP8300D61U 8262G8043800178 8320G176 8316G303 8342G1SCE 43800178EF8344G70 8210G22 WBIS8551A301 EF8320GOO3MS60100035 35500382 8344G080 8300D68F EF8342G20 NKS374A090MS 88200007 5419102851800021 EF8210G4 HT8262G13E HT8320G138300G076U 43004419 19200002 8327G001 19090017 43004155 SCG551A002MS 5410088443800178 30400008 30400007 EF8401B101 88100140 54191027 8551A017MS 8551G401MS8210 8344G080 8300D68F 8210G2 SCE238 EF8210G004NFB316E044V K302353 55192011 EF8210G8EF8210G4 EF8210G22 EF8210G89 3439311445000512 8210G207 8262G220　 342030818345G001 EFHB8316G14V 60100037 601000058327G001 HT8344G76MO 8262G002 SCG353A051EF8003G1 EF8215B80 EF8342G20 12100134EFG8320G8 EFG8320G4 EFG8320G22 NFB327A002 EF8210G002 EV8551G453 EV8327G52 SCE238A005 13100244 WBIS8316A301 EF8320G194 SCE263B206V8360G74 WBIS8316A304 WBIS8314br /> ASCO电磁阀，二位四通电磁阀线圈断电时，电磁吸力为零，副阀阀塞和支铁芯由于弹簧作用向上提起，副阀打开，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力。
