Mavavu ampira amagwira ntchito yofunika kwambiri pamoyo watsiku ndi tsiku popeza amagwiritsidwa ntchito tsiku lililonse monga panjinga kapena magalimoto, ndege za jeti kapena mafakitale aliwonse. Mavavu amabwera mosiyanasiyana komanso mosiyanasiyana, ndipo valavu iliyonse imakhala ndi kukula kwake, ntchito yake, komanso kagwiritsidwe ntchito kake.

Makampaniwa agwiritsa ntchito kwambirima valve a mpira, ndikuwonetsetsa kuti ma valvewa akugwirabe ntchito panthawi yogwira ntchito, ndi bwino kuwasunga asanawonongeke. Kuyeretsa nthawi zonse ndi kuthira mafuta kuti zitsimikizire kuti zimagwira ntchito bwino ndizofunikira pa moyo wautali.
Mavavu awa amapezeka m'matupi asanu acholinga chonse, kuphatikiza matupi atatu, matupi awiri, kulowa m'thupi limodzi, thupi logawanika, ndi ma welded.mavavu. Makhalidwe otsatirawa amawapangitsa kukhala chisankho chabwino kwambiri chowongolera machitidwe osiyanasiyana, ndipo nthawi zina amaposa valavu ina iliyonse yomwe ili ndi mphamvu zochepa pakugwedeza ntchito.

Ubwino wa mavavu a mpira

Amapereka ntchito zowonetsera kutayikira,
kutsegula ndi kutseka mwachangu,
Poyerekeza ndi ma valve a pachipata, ndi ochepa kwambiri kukula kwake,
Poyerekeza ndi ma valve a pachipata, ndi opepuka,
Ma valve a zipata kapena globe alibe kusinthasintha kwa mapangidwe angapo, chifukwa chake amachepetsa kuchuluka kwa ma valve omwe amafunikira,
Opangidwa mosiyanasiyana ndi mawonekedwe, mavavuwa amapereka kusinthasintha kwa kusankha,
Ma valve apamwamba kwambiri amapereka ntchito yotetezeka pansi pa kutentha kwakukulu ndi kupanikizika kwakukulu, ndi
Ali ndi mphamvu zochepa kuposa ma valve ena.
Kuipa kwakukulu kwa ma valve awa ndi awa:

Sinthani malo a chogwirira cha valve,
sungagwiritsidwe ntchito popumira, ndi
Ma valve omwe ali ndi makina oyendetsa magetsi ayenera kuikidwa molunjika.
Ku Pntek Engineers, tili ndi ma valve ambiri omwe amapangidwa kuti akwaniritse zosowa za makasitomala, kuphatikizapo ma valve a mpira omwe amapangidwa ndi zamakono zamakono komanso oyenerera ntchito zovuta. Mavavu athu ndi osavuta kugwiritsa ntchito, osavuta kusamalira, kukonza pang'ono, apamwamba kwambiri komanso osagwirizana ndi dzimbiri.
