Kamuva, ubuchwepheshe be-valve nabo bathuthukiswa.Ngokuthuthukiswa kobuchwepheshe bokukhiqiza ama-valve ensimbi, kwamukelwa izindlela ezintsha zokuphonsa futhi izinto zokwakha zathuthukiswa.I-valve yensimbi yamukela imishini yokusebenza enamandla, futhi ukunemba nakho sekuthuthukisiwe.
Ukuze ubhekane nokushoda kwamanzi amapayipi okwakha, imithetho yomsindo ehlobene nezinsiza zomkhiqizo, kanye nokuthuthukiswa kokuphepha kwegesi, amavalvu afaka ama-valve avimbela ukugqwala amapayipi okuhambisa amanzi, ama-valve anomsindo ophansi wokunciphisa umsindo wokugeleza, ompompi abanezisekelo, kanye ukuhlanganisa.Ukuguqulwa kwamapulaki egesi kasilika.
Manje sesiqalileimishini ye-valve ekhethekilefuthiumshini wokulungisa i-valveengakwenza lokhu.Ngemuva kokuthuthukiswa okuningana, umthamo wamanje wethuluzi lokusika ungafika ku-10mm.Isebenza kahle, ikahle, izinzile futhi inokwethenjelwa.Inikezelwe ekucubunguleni insimbi eyenziwe ngomgunyathi, insimbi ekhonjiwe, amavalvu esango, ama-globe valves, ama-Butterfly valves, izindololwane, njll.
