Ukuphonononga ukusetyenziswa kweiflange yaseTshayina iqhagamshele ivalve yebhabhathane ephakathikumashishini afana nokwakha kunye nokugcinwa kwamanzi
I-Chinese flange eqhagamshele i-midline butterfly valve sisixhobo esisetyenziswa ngokuqhelekileyo ukulawula ukuhamba kunye noxinzelelo lwe-fluid medium. Kumashishini afana nokwakhiwa kunye nokugcinwa kwamanzi, i-centerline butterfly valves nayo isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo. Eli nqaku liza kuphonononga ukusetyenziswa kweiflange iqhagamshelene midline butterfly valves kumashishini afana nolwakhiwo kunye nokugcinwa kwamanzi e China.
