Ama-valve epulaki e-DBB agcina isikhala, anciphisa isidingo sezinhlelo ezibizayo ezinama-valve amaningi, futhi anikeze amandla okuvuza u-zero ukusuka phezulu kuya phansi. ukuvimba nokopha kanye nokuhlukaniswa okuphindwe kabili kanye nevalvu yokusiza ingasetshenziselwa izinhlelo zokusebenza nezimakethe ezihlukahlukene, njengegesi yemvelo ewuketshezi, i-petrochemical, ukudluliselwa nokugcinwa, inqubo yemboni yegesi, umqondisi namavalvu ahlukahlukene kumapayipi awuketshezi, kanye nepayipi lomkhiqizo ocolisisiwe.I-DBB i-valve yepulaki iklanyelwe ukusetshenziswa kumapayipi oketshezi anemigudu nezici zokuphuma okukabili kanye nezindawo zokuhlala ezivikelwe ngokugcwele.
I-valve yepulaki ye-DBB isetshenziswa ezinhlelweni ezidinga ukuhlukaniswa okubalulekile ukuze kuqinisekiswe ukuthi akukho ukuvuza okwenzekayo. Yiziphi izinhlobo zokukhetha ezincike ohlotsheni lohlelo lokusebenza nesevisi.Isibonelo, endleleni yamanzi noma eduze kwedolobha lesevisi ye-liquid, i-valve yokwandisa kabili Ukuthuthukiswa kwekhono le-DBB lokuzihlukanisa okubalulekile, njengoba zinikeza uphawu lomshini oluqinile olukhuphuka nomfula ophansi ngesikhathi esifanayo, ngokuvamile aluthintwa izinguquko zengcindezi noma ukudlidliza.
