Makulidwe a zipatso za chibayo amagwiritsidwa ntchito kwambiri mu mankhwala, mafuta, ma metallingorgy, magetsi amagetsi ndi minda ina yamafakitale yamalamulo ndi mphamvu zamadzimadzi. Itha kukwaniritsa chowongolera chosinthika ndikuwonetsetsa kukhazikika ndi kudalirika kwa njirayi.
Mawonekedwe:
1. Kudalirika kwakukulu : valavu yovomerezeka yamimba imapangidwa ndi zida zapamwamba kwambiri, zimatsutsana bwino ndi kutentha kwambiri, ndipo zitha kugwira ntchito mokhazikika kwa nthawi yayitali.
2. Kukonza mosavuta : Celumetic Berve wowongolera amakhala ndi kapangidwe kosavuta ndipo ndikosavuta kusunga, komwe kumachepetsa nthawi yokonza ndi ndalama.
3. Ntchito yofunikira kwambiri : valavu yoyendetsera ma piamo yaying'ono ndiyoyenera kuwongolera madzi oyendetsa madzi, mafuta, mphamvu yamagetsi, ndi minda ina, ndipo imakwaniritsa zofunikira zosiyanasiyana ntchito zosiyanasiyana.
Zogulitsa zazikuluzikulu zimaphatikizapo valavu yowongolera ya chibayo, valavu ya mpira, valavu yamagetsi, valavu yopendekera, yopatsa chidwi.
