I. Ngokusho kwamandla
1. Ivalvu ezenzakalelayo: thembela emandleni ayo okusebenza ivalvu.Njenge-valve yokuhlola, i-valve yokunciphisa ingcindezi, i-valve yesicupho, i-valve yokuphepha, njalonjalo.
2. I-valve yokushayela: thembela kubasebenzi, ugesi, i-hydraulic, i-pneumatic, namanye amandla angaphandle ukuze usebenzise i-valve.Okufana ne-globe valve, i-throttle valve, i-valve yesango, i-disc valve, i-valve yebhola, i-plug valve, njalonjalo.
II.Ngokwezici zesakhiwo
1. Isimo sokuvala: ucezu lokuvala luhamba phakathi nendawo yesihlalo.
2. Isimo sesango: ucezu lokuvala luhamba eduze komugqa ophakathi nendawo ukuya esihlalweni.
3. Isimo sepulaki: ucezu oluvalayo luyi-plunger noma ibhola elizungeza umugqa omaphakathi.
4. I-Swing-open shape: ucezu oluvalayo luzungeza i-eksisi ngaphandle kwesihlalo.
5. Umumo wediski: ilungu elivalayo idiski elizungeza i-eksisi ngaphakathi kwesihlalo.
6. I-valve yesilayidi: ingxenye yokuvala ishelela iqonde ku-perpendicular esiteshini.
III.Ngokusho ukusetshenziswa
1. Ukuvula/ukuvala: kusetshenziselwa ukunqamula noma ukuxhuma indawo yamapayipi.Njenge-valve yokumisa, i-valve yesango, i-valve yebhola, i-plug valve, njalonjalo.
2. Ukulungiswa: kusetshenziselwa ukulungisa ingcindezi noma ukugeleza kwe-medium.Njenge-valve yokunciphisa ingcindezi, ne-valve yokulawula.
3. Ngokusatshalaliswa: kusetshenziselwa ukushintsha isiqondiso sokugeleza komsebenzi omaphakathi, wokusabalalisa.Njengeqhude elinezindlela ezintathu, i-valve yokumisa yezindlela ezintathu, njalonjalo.
4. Ukuhlola: kusetshenziselwa ukuvimbela imidiya ukuthi ingabuyeli emuva.Njengama-valve okuhlola.
5. Ngokuphepha: lapho ingcindezi emaphakathi idlula inani elishiwo, khipha okuphakathi nendawo ukuze uqinisekise ukuphepha kwezinto zokusebenza.Njenge-valve yokuphepha, ne-valve yengozi.
6. Ngokuvinjwa kwegesi kanye nokukhipha amanzi: gcina igesi futhi ungafaki i-condensate.Njenge-valve yesicupho.
IV.Ngokwendlela yokusebenza
1. I-valve yezandla: ngosizo lwesondo lesandla, isibambo, i-lever, i-sprocket, igiya, i-worm gear, njll., sebenzisa i-valve ngesandla.
2. Ivalvu kagesi: isebenza ngogesi.
3. I-valve ye-pneumatic: enomoya ocindezelwe ukuze isebenze i-valve.
4. I-valve ye-hydraulic: ngosizo lwamanzi, uwoyela, nolunye uketshezi, dlulisa amandla angaphandle ukuze asebenzise i-valve.
V. Ngokushoingcindezi
1. I-vacuum valve: i-valve enengcindezi ephelele engaphansi kuka-1 kg/cm 2.
2. I-valve ye-low-pressure: ukucindezela okuphansi okungaphansi kuka-16 kg / cm 2 valve.
3. I-valve yokucindezela okuphakathi: ukucindezela okulinganiselwe 25-64 kg / cm 2 valve.
4. I-valve ephezulu yokucindezela: ukucindezela okulinganiselwe 100-800 kg / cm 2 valve.
5. Umfutho ophakeme kakhulu: ingcindezi yokuzisholo ukuya noma engaphezu kuka-1000 kg/cm amavalvu angu-2.
VI.Ngokusho kweizinga lokushisakwe medium
1. I-valve evamile: ifanele i-valve enokushisa okuphakathi kokusebenza okungu- -40 kuya ku-450 ℃.
2. I-valve yokushisa ephezulu: ilungele i-valve enokushisa okuphakathi kokusebenza okungu-450 kuya ku-600 ℃.
3. I-valve ekwazi ukumelana nokushisa: ilungele i-valve enezinga lokushisa eliphakathi nendawo elisebenza ngaphezu kuka-600℃.
4. I-valve yokushisa ephansi: ilungele i-valve enezinga lokushisa eliphakathi nendawo eliphakathi kuka -40 kuya ku -70 ℃.
5. I-valve ye-Cryogenic: ifanele i-valve enezinga lokushisa eliphakathi nendawo eliphakathi kuka -70 kuya ku -196 ℃.
6. I-valve yokushisa ephansi kakhulu: ilungele i-valve enezinga lokushisa eliphakathi nendawo elingaphansi -196℃.
VII.Ngokusho kobubanzi obujwayelekile
1. I-valve yobubanzi obuncane: ububanzi obuncane obungaphansi kuka-40 mm.
2. I-valve yobubanzi obumaphakathi: ububanzi obuyigama obungu-50 kuya ku-300 mm.
3. Ama-valve obubanzi obukhulu: ububanzi obuyigama obungama-350 kuya ku-1200 mm.
4. Amavalvu obubanzi obukhulu kakhulu: amadayamitha okuzisholo angaphezu kuka-1400 mm.
