yang'anani pakupanga ma valve oyandama.Mapangidwe oyandama amatanthauza mphete ziwiri zapampando zimagwiritsidwa ntchito pothandizira mpira mu valavu yamtundu woyandama.Kapangidwe kameneka kamapangitsa mpirawo kuyandama kapena kusuntha molunjika pampando wokhala pamwamba.Mapangidwewa ndi oyenerera kukula kwazing'ono ndi ma valve otsika otsika.
Mpira wolimba umapangidwa ndi makina opangidwa ndi compact kapena forging.Mpira wolimba nthawi zambiri umatengedwa ngati njira yabwino kwambiri yothetsera moyo wanu wonse.Ndipo mipira yolimba imagwiritsidwa ntchito makamaka pazovuta kwambiri.
Mpira wopanda pake umapangidwa ndi mbale yachitsulo yokhotakhota kapena machubu achitsulo osapanga dzimbiri.Mpira wopanda pake umachepetsa katundu wozungulira komanso mpando wa valve chifukwa cha kulemera kwake, zomwe zimathandiza kuwonjezera moyo wautumiki wa mpando wa valve.
Mpira mu trunnion wokwera valavu ya mpira susuntha chifukwa mpira wa trunnion wa valavu uli ndi tsinde lina pansi kuti likhazikike pomwe mpirawo uli.Mipira yamtundu wa trunnion imagwiritsidwa ntchito makamaka pazovuta kwambiri komanso ma valve akulu akulu akulu.
