Bambanci na farko tsakanin 4/2-way da 5/2-way solenoid valves ya ta'allaka ne a cikin tsarin su na tashar jiragen ruwa da adadin matsayi da zasu iya kasancewa:
4/2-Way Solenoid Valve:
Wannan nau'in bawul yana da tashoshi huɗu da matsayi biyu.
Yawanci ya ƙunshi tashar shiga mai shiga guda ɗaya, tashoshin silinda biyu, da tashar shaye-shaye ɗaya.
Bawul ɗin yana sarrafa kwararar iskar zuwa na'urar kunna huhu (kamar silinda) ta hanyar haɗa mashigar zuwa ɗaya daga cikin tashoshin silinda (ba da damar iska ta gudana cikin na'urar kunnawa) ko ta haɗa ɗaya daga cikin tashoshin silinda zuwa tashar shaye-shaye (ba da damar iska ta tsere kuma mai kunnawa ya ja da baya).
5/2-Way Solenoid Valve:
Wannan nau'in bawul yana da tashoshin jiragen ruwa guda biyar da matsayi biyu.
Yawanci ya ƙunshi tashar shiga mai shiga guda ɗaya, tashar jiragen ruwa na Silinda biyu, da tashoshin shaye-shaye biyu.
Kamar bawul ɗin-hanyar 4/2, yana sarrafa kwararar iska zuwa mai kunna huhu, amma yana ba da ƙarin sassauci saboda yana da tashar jiragen ruwa guda biyu. Wannan na iya zama da amfani a wasu aikace-aikace inda ake buƙatar shaye-shaye mai sauri ko kuma na'urori daban-daban.
Game da dual coil solenoid bawul:
Dual coil solenoid bawul nau'in bawul ɗin solenoid ne wanda ke buƙatar nau'ikan coils guda biyu don aiki. Kowane coil yana da alhakin sarrafa bawul ta hanya ɗaya. Lokacin da coil ɗaya ya sami kuzari, yana matsawa bawul ɗin zuwa matsayi ɗaya, yayin da ɗayan ya sami kuzari, yana jujjuya bawul ɗin zuwa ɗayan.
