I-valve yesango lommese ifanele udaka kanye nombhobho ophakathi oqukethe i-fiber, futhi ipuleti layo le-valve lingasika izinto ze-fiber endaweni ephakathi; isetshenziswa kabanzi ekudluliseni udaka lwamalahle, i-pulp yamaminerali kanye nepayipi le-slag elenziwe ngephepha. I-valve yesango lommese isuselwa ku-valve yesango, futhi inezinzuzo zayo ezihlukile kanye nokungalungi.1, Ingumkhiqizo we-valve okhethwayo wepayipi le-slurry, slurry kanye ne-pulp. 2. Isakhiwo esilula, ivolumu encane, isisindo esincane kanye nokufakwa okulula. Okubi kwe-valve yesango lommese: ingasetshenziswa kuphela kumbhobho onengcindezi ephansi. I-valve yesango lommese isetshenziswa kakhulu kumbhobho we-slurry, okungashiwo ukuthi i-valve ekhethekile yombhobho we-slurry.
