Iivalvu zokujonga i-waferZikwaziwa ngokuba ziivalvu ze-backflow, iivalvu ze-backstop, kunye neevalvu ze-backpressure. Ezi ntlobo zeevalvu zivulwa kwaye zivalwe ngokuzenzekelayo ngamandla aveliswa kukuhamba kwesixhobo ngokwaso kwipayipi, eyinxalenye yohlobo lwevalvu ezenzekelayo.
Ivalvu yokukhangela ixhomekeke ekuhambeni kwesixhobo ngokwaso kwaye ivula kwaye ivale ngokuzenzekelayo i-flap yevalvu, esetyenziselwa ukuthintela ivalvu yokubuyela umva ephakathi, eyaziwa ngokuba yivalvu yokujonga, ivalvu yokujonga, ivalvu yokubuyela umva, kunye nevalvu yoxinzelelo lomqolo. Ivalvu yokujonga yeyohlobo lwevalvu ezenzekelayo, indima yayo ephambili kukuthintela ukubuyela umva kwemidiya, ukuthintela ukuguquka kwepompo kunye nemoto yokuqhuba, kunye nokukhupha imidiya yesikhongozeli. Iivalvu zokujonga zingasetyenziselwa ukunika uxinzelelo olunokunyuka luye kuxinzelelo olungaphezulu kwenkqubo yenkqubo yokuncedisa ukubonelela ngombhobho wokubonelela. Ivalvu yokujonga inokwahlulwa ibe yivalvu yokujonga i-swing (ngokweziko lokujikeleza komxhuzulane) kunye nevalvu yokujonga i-lift (ehamba ecaleni kwe-axis).
Okokuqala, ukusetyenziswa kwevalvu yokujonga ivalvu yokujonga i-clip-on efakwe kwinkqubo yepayipi, indima yayo ephambili kukuthintela ukubuyela umva kwemidiya, ivalvu yokujonga luhlobo lwevalvu oluzenzekelayo oluxhomekeke kuxinzelelo lwemidiya ukuvula nokuvala. Ivalvu yokujonga i-Clamp ifanelekile kuxinzelelo oluqhelekileyo lwe-PN1.0MPa ~ 42.0MPa, iClass150 ~ 25000, ububanzi obuqhelekileyo be-DN15 ~ 1200mm, i-NPS1/2 ~ 48, ubushushu bokusebenza -196 ~ 540 ℃ bemibhobho eyahlukeneyo, esetyenziselwa ukuthintela ukubuyela umva kwemidiya. Ngokusebenzisa ukukhethwa kwezinto ezahlukeneyo, ingasetyenziswa emanzini, umphunga, ioyile, i-nitric acid, i-acetic acid, i-oxidizing media enamandla kunye ne-uric acid kunye nezinye izinto.
Izinto eziphambili zevalvu yokujonga i-wafer yintsimbi yekhabhoni, intsimbi enobushushu obuphantsi, intsimbi ye-duplex (SS2205/SS2507), i-titanium alloy, i-aluminium bronze, i-Inconel, i-SS304, i-SS304L, i-SS316, i-SS316L, intsimbi ye-chrome-molybdenum, i-Monel (400/500), i-20# alloy, i-Hastelloy kunye nezinye izinto zesinyithi.
Okwesithathu, imigangatho kunye nemigangatho yevalvu yokujonga i-wafer
Uyilo: API594, API6D, JB/T89372,
Ubude bobuso ngobuso：API594、API6D、DIN3202、JB/T89373、

Uvavanyo kunye nomgangatho wovavanyo: API598, JB/T90925
Iiflanges zePiping：JB/T74~90、GB/T9112-9124、HG20592~20635、SH3406、ANSI B 16.5、DIN2543-2548、GB/T13402、API605、ASMEB16.47
Okwesine, iimpawu zesakhiwo sevalvu yokujonga i-pinch
1. Ubude besakhiwo esifutshane, ubude besakhiwo saso yi-1/4 ~ 1/8 kuphela yevalvu yokujonga i-swing flange yendabuko.
2. Umthamo omncinci, ubunzima obuphantsi, ubunzima bawo kuphela yivalvu yokujonga iflange yendabuko 1/4 ~ 1/2
3. I-valve flap ivala ngokukhawuleza, uxinzelelo lwesando samanzi luncinci
4. Ingasetyenziswa imibhobho ethe tye okanye ethe nkqo, kulula ukuyifaka
5. Indlela yokuhamba kakuhle, ukumelana nolwelo oluphantsi
6. Isenzo esinovakalelo, ukusebenza kakuhle kokutywina
7. I-disc stroke imfutshane, i-closing impact incinci
8. Ulwakhiwo lulonke lulula kwaye luncinci, kwaye imilo intle
9. Ubomi benkonzo ende kunye nokusebenza okuthembekileyo
ezintlanu. Ukusebenza kokutywina kwevalvu yokujonga i-wafer Ivalvu yokujonga i-wafer etywiniweyo ethambileyo inokufikelela ekungavuzini, kodwa ivalvu yokujonga i-wafer etywiniweyo ayisiyovalvu yokuvuza. Inezinga elithile lokuvuza. Ngokomgangatho wokuhlola we-API598, kwivalvu yokujonga enesihlalo sesinyithi, ngobukhulu be-DN100, izinga lokuvuza kolwelo ngomzuzu yi-12CC.
