Vavu yagulugufe yogwira ntchito kwambiri ndi valavu yamakampani yowongolera bwino kuyenda.
1. Kupanga mavavu amtundu wa Wafer kumachepetsa zofunikira za malo ndi nthawi yoyika.
2. Mavavu agulugufe omwe amagwira ntchito kwambiri nthawi zambiri amapangidwa ndi zinthu monga chitsulo chosapanga dzimbiri, chitsulo cha kaboni kapena ma alloys ena osachita dzimbiri kuti atsimikizire kukana kwa dzimbiri komanso kutentha kwambiri.
3. Mpando wa valavu wa gulugufe wochita bwino kwambiri ndiye wosiyana kwambiri ndi valavu wamba wagulugufe wamba.
4. Kusindikiza kuwirikiza kawiri: Ma valve agulugufe ochita bwino kwambiri amapereka kusindikiza kwapawiri, komwe kumatha kusindikiza bwino mbali zonse ziwiri.
