Njengenxalenye yolawulo oluphambili kwiinkqubo ze-hydraulic, ukusebenza kunye nokuthembeka kwe-hydraulic solenoid valves kuxhomekeke kakhulu kwizinto ezikhethiweyo. Ukukhethwa kwezinto ezifanelekileyo akuchaphazeli kuphela ukunyanzeliswa kwe-valve ye-solenoid, ukuxhatshazwa kwe-corrosion, kunye nobomi benkonzo, kodwa kuchaphazela ngokuthe ngqo ukusebenza okuzinzile kwenkqubo yonke ye-hydraulic.
Izixhobo eziphambili ze-hydraulic solenoid valves zinokuhlelwa ngokwamaqela amathathu: imathiriyeli yomzimba wevalvu, imathiriyeli yokutywina, kunye nemathiriyeli yekhoyili ye-solenoid. Umzimba wevalvu, njengomthwalo-ulwakhiwo oluthwele ivalve ye-solenoid, wenziwe ngentsimbi ephezulu{2}}efana nobhedu, intsimbi engatyiwa, okanye ialuminiyam. Ubhedu lusetyenziswa kakhulu kwiinkqubo ezisezantsi- naphakathi{5}noxinzelelo lwehydraulic ngenxa yokusebenza kwayo okugqwesileyo, ukunganyangeki komhlwa, kunye namandla aphakathi. Insimbi engagqwali (efana ne-304 okanye i-316) ilungele{9}}uxinzelelo oluphezulu, iimeko ezingqongileyo ezinokonakalisa kakhulu, njengakummandla wobunjineli bamachiza kunye nolwandle. Imizimba yevalvu ye-aluminiyam, ngenxa yeempawu zayo ezikhaphukhaphu, isoloko isetyenziswa kubunzima{11}}izixhobo ezibuthathaka.
Ukukhethwa kwezinto zokutywina kuchaphazela ngokuthe ngqo ukusebenza kokutywinwa kunye nokuqina kwe-valve ye-solenoid. Izinto eziqhelekileyo zokutywinwa ziquka irabha ye-nitrile (NBR), i-fluororubber (FKM), kunye ne-polytetrafluoroethylene (PTFE). I-NBR ibonelela nge-oyile egqwesileyo kunye nokunganyangeki kwaye ifanelekile kwimo engqongileyo yolwelo oluqhutywa ngamanzi. I-FKM (enje ngeViton) inokumelana namaqondo obushushu aphezulu kunye nemithombo yeendaba ezibukhali zekhemikhali, iyenze ifanele -ubushushu obuphezulu okanye iimeko zokusebenza ezidleka kakhulu. I-PTFE, ne-coefficient yayo ephantsi kakhulu yokukhuhlana kunye nokungazenzisi kweekhemikhali okugqwesileyo, isoloko isetyenziselwa{5}}izitywina ezichanekileyo okanye izitywino zemidiya eyodwa.
Ikhoyili ye-solenoid idla ngokuba nenxeba -ngocingo olufakwe kwimagnethi olugqunyiweyo kwaye igqunywe kubushushu obuphezulu-iqondo lobushushu{2}}iplastiki ekwaziyo ukumelana okanye i-epoxy resin ukuqinisekisa ukusebenza okuzinzileyo naxa ivalve ye-solenoid inikwe amandla ixesha elide.
Isishwankathelo, ukukhethwa kwezinto eziphathekayo ze-hydraulic solenoid valves kufuna ukuqwalaselwa ngokubanzi koxinzelelo lokusebenza, iimpawu zemidiya, uluhlu lweqondo lokushisa, kunye neendleko zokuqinisekisa ukuthembeka kunye nobomi obude kwiimeko ezahlukeneyo zesicelo.
