Ivalvu yesango lommese ilungele udaka nepayipi eliphakathi eliqukethe i-fiber, futhi ipuleti layo levalvu lingakwazi ukusika impahla yefiber phakathi nendawo;isetshenziswa kakhulu ekudluliseni udaka lwamalahle, i-mineral pulp kanye ne-papermaking slag slurry pipeline.Ivalvu yesango lommese iphuma kuvalvu yesango, futhi inezinzuzo zayo eziyingqayizivele kanye nebubi.1, Iwumkhiqizo wevalvu okhethwayo wamapayipi odaka, oludaka kanye ne-pulp.2. Isakhiwo esilula, ivolumu encane, isisindo esincane nokufakwa okulula.Ukungalungi kwe-valve yesango lommese: ingasetshenziswa kuphela epayipini lokucindezela okuphansi.Ivalvu yesango lommese isetshenziswa kakhulu epayipini elidaka, okungashiwo ukuthi liyivalvu ekhethekile yamapayipi odaka.
