Manual bhora vharafu, butterfly vharafu uye plug vharafu imhando imwechete yevharuvhu. Musiyano ndewekuti chikamu chekuvhara chevhavha yebhora ibhora, rinotenderera rakapoteredza mutsara wepakati wemuviri wevhavha kuti uwane kuvhura nekuvhara. Ivhavha yebhora inonyanya kushandiswa kucheka, kugovera uye kushandura nzira yekuyerera kwepakati mupombi. Ivhavhavha yebhora-matatu imhando itsva yevharuvhu yakashandiswa zvakanyanya mumakore achangopfuura. Rudzi urwu rwevharuvhu kazhinji runofanira kuisirwa yakatwasuka mupombi.

NSW valve kambani bhuku rinoyangarara bhora vharafu chigaro chine chisimbiso chakanaka. Mhete yekuvharisa yevharuvhu yebhora inonyanya kugadzirwa nezvinhu elastic sePTFE (RPTFE, NYLON, DEVLON, PEEK etc.). Iyo yakapfava yekuisa chisimbiso chimiro chiri nyore kuve nechokwadi chekuisa chisimbiso, uye sezvo iyo yepakati pressure inowedzera, iyo yekuisa chisimbiso yevhavha yebhora inowedzera. The stem chisimbiso chakavimbika. Kana vharuvhu yebhora yakavhurwa uye yakavharwa, hunde yevharuvhu inongotenderera chete uye haifambi kumusoro uye pasi. Iyo valve stem packing seal haisi nyore kukuvara. Simba rekuvhara revhavha stem reverse seal rinowedzera nekuwedzera kwepakati pekumanikidza. Nekuti PTFE uye zvimwe zvinhu zvine yakanaka yekuzvizora zvivakwa, friction kukuvadzwa nebhora revharuvhu bhora idiki, uye vharafu yebhora ine hupenyu hurefu hwebasa. Iyo yekushandisa modhi inogona kuve yakashongedzerwa nepneumatic, yemagetsi, hydraulic uye mamwe madhiraivha maitiro ekuona kure kure uye otomatiki kushanda. Iyo bhora vharafu chiteshi inotsvedzerera uye inogona kutakura viscous fluid, slurries uye yakasimba zvimedu.

Manual floating ball valve imhando yevharuvhu yakabuda muma1950s. Muhafu yezana ramakore, vharuvhu yebhora yakagadzira chikamu chikuru chevharuvhu. Ivhavha yebhora inonyanya kushandiswa kucheka kana kubatanidza svikiro, uye inogonawo kushandiswa kugadzirisa mvura uye kutonga. Iyo Segment ball valve (V notch ball valve) inogona kuita yakanyatso kuyerera kuyerera uye kutonga, uye nzira nhatu bhora vharafu inoshandiswa kugovera yepakati uye kushandura mafambiro epakati. Manual bhora mavharuvhu anodaidzwa zvakanyanya zvichienderana nekutyaira kwevharuvhu yebhora nekutenderedza vhiri reruoko kana mubato.
