Kwindibano yocweyo ye-Jinbin, iivalve zebhabhathane ezintlanu ezinobubanzi obukhulu obuphindwe kabini ziye zahlolwa. Imilinganiselo yabo yi-DN2200, kwaye imizimba yevalvu yenziwe nge-iron ductile. Ivalve nganye yebhabhathane ixhotyiswe nge actuator yombane. Okwangoku, ezi zininziiivalve butterflyziye zahlolwa kwaye zamkelwa, kwaye zilindele ukupakishwa kunye nokuthunyelwa.

Ngokungafaniyo neevalvu zebhabhathane eziqhelekileyo (apho isiqu sevalve sidibana nombindi wepleyiti yebhabhathane kunye nomzimba wevalve) okanye ivalve yebhabhathane ene-eccentric enye (apho isiqu sevalve sitenxa kumbindi wepleyiti yebhabhathane), iivalve zebhabhathane ezineeccentric eziphindwe kabini zamkela uyilo oluphindwe kabini “lwe-axi ye-valve yesikhondo umzimba wevalvu”.

Esi sakhiwo senza ukuba ipleyiti yebhabhathane idibane nesihlalo sevalve kuphela xa isondele ekuvaleni ngexesha lokuvula nokuvala. Ngethuba lokuphumla kwe-stroke, i-butterfly plate ihlukaniswe ngokupheleleyo kwisihlalo se-valve, inciphisa kakhulu i-friction kunye nokugqoka kwendawo yokutywina. Ngokukodwa kwiimeko ezinobubanzi obukhulu, kunokuphepha "ukungqubuzana okunzima" kwindawo yokutywina okubangelwa ubunzima bokuzimela kwepuleti yebhabhathane okanye uxinzelelo oluphakathi, ukwandisa ngokubonakalayo ubomi benkonzo yesibini sokutywina, esihlala singaphezulu kwe-30% ubude kunalowo we-valve ye-butterfly yentsimbi enye.

Ipleyiti yebhabhathane yevalve yebhabhathane yombane enobubanzi obukhulu yamkela uyilo olulungelelanisiweyo. Xa ivuliwe ngokupheleleyo, i-butterfly plate inendawo encinci yokuthintela phakathi kunye ne-coefficient yokumelana nokuhamba okuphantsi, okunokunciphisa ilahleko yamandla yenkqubo yombhobho. Kwimibhobho emikhulu enobubanzi be-DN1000 okanye ngaphezulu (njengemigca ye-trunk yonikezelo lwamanzi asezidolophini kunye neplanti yombane ejikeleza iinkqubo zamanzi), ukusetyenziswa kwamandla kweseti yempompo kugcinwe kakhulu.

Isixhobo somzimba we-valve sinokukhethwa kwi-iron ductile (kumanzi kamasipala), i-carbon steel (ye-oyile ye-industrial), okanye i-stainless steel (kwi-corrosive media) ngokusekelwe kwiimpawu ze-medium. Umphezulu we-butterfly plate unokutshiza-welded kunye ne-wear-resistant layer (njenge-tungsten carbide), enokumelana nokukhukuliseka kweendaba eziqulethe inani elincinci leengqungquthela (ezifana nesihlabathi kunye ne-slag). Ukuhambisa ulwelo oluqulethe ukungcola okunje ngamanzi amdaka kunye ne-ash slurry, ubomi bayo benkonzo ngama-2 ukuya ku-3 amaxesha eevalve zebhabhathane eziqhelekileyo.

I-diameter enkuluivalve yebhabhathane eccentric kabini, ngokusungulwa kwezinto ezintsha, ilungelelanise ulawulo lokuhamba, ukutywinwa kokusebenza kunye nobomi bokusebenza kwemibhobho yobubanzi obukhulu. Kuye kwaba sisisombululo esisebenzayo sokutshintsha iivalvu zesango zendabuko kunye neevalve zebhola kwiinkqubo eziphezulu kunye neziyinkimbinkimbi eziphakathi kumasipala, amandla, ukugcinwa kwamanzi, i-industrial kunye nezinye iindawo. Ilungele ngokukodwa iimeko zokusebenza zexesha elide ezinovakalelo kusetyenziso lwamandla kunye neendleko zokugcina.
