Ukukhetha ivalve efanelekileyo yenkqubo yombhobho ichaphazela ngokuthe ngqo ukhuseleko lokusebenza, ukusebenza kakuhle, ukugcinwa rhoqo, kunye nolawulo lweendleko zexesha elide. Phakathi kweentlobo ezininzi zevalve ezikhoyo namhlanje, iIsango lokutywina leSitulo se-Elasticiye yaba sisisombululo esithandwayo kwiinkqubo zokubonelela ngamanzi, iindawo zokucocwa kwamanzi amdaka, iipayipi zoshishino, iinkqubo zokukhusela umlilo, kunye neeprojekthi zobunjineli zikamasipala.
Esi sikhokelo esibanzi sichaza ukuba yintoni ivalve yokutywina yesihlalo sokutywina, indlela esebenza ngayo, iingenelo zayo zesakhiwo, izicelo eziqhelekileyo, ukuqwalaselwa kokufakela, iindlela zokugcina, ukhetho lwezinto eziphathekayo, kunye neengcebiso zokuthenga. Nokuba uyinjineli, umsasazi, ikontraki, okanye umphathi weprojekthi, eli nqaku libonelela ngeembono ezisebenzayo ukukunceda wenze izigqibo ezizizo.
Isango lokutywina leSitulo se-Elastic yivalvu ehleliyo ehleliyo eyenzelwe ukubonelela ngokusebenza okuthembekileyo kokuvala kwiinkqubo zokulawula ulwelo. Ngokungafaniyo neevalvu zesango ezihlala ngesinyithi, le valve isebenzisa isango eligqunywe nge-elastomer ukufezekisa ukutywinwa okungqongqo kunye nokumelana ngcono ngokuchasene nokuvuza.
Ivalve isetyenziswa ngokuqhelekileyo kwiinkqubo zokubonelela ngamanzi ngenxa yokuba inokugcina ukusebenza kokutywina okugqwesileyo naphantsi kweemeko zoxinzelelo ezahlukeneyo. Iweji ekwaziyo ukumelana nerabha egqunywe ngerabha ikhubaza kancinane xa ivaliwe, iqinisekisa ukudibana ngokupheleleyo nesitulo sevalvu kunye nokunciphisa ukuvuza.
Ezi valves ziyaziwa ngokubanzi ngokuhlala kwazo, ukuxhathisa ukubola, ukusebenza kwetorque ephantsi, kunye nokunciphisa iimfuno zokugcinwa.
Indlela yokusebenza ithe ngqo. Xa i-handwheel okanye i-actuator ijikeleza, isiqu sihambisa isango ngokuthe nkqo. Njengoko isango lisihla, i-wedge enerabha egqunywe ngerabha ixinzeleleka kwisitulo sevalvu, yenze itywina eliqinileyo.
Xa ivuliwe ngokupheleleyo, isango lihamba ngokupheleleyo ngaphandle kwendlela yokuhamba, ivumela ukunyakaza okungathintekiyo kwamanzi kunye nokulahlekelwa kwengcinezelo encinci.
