Makina opangira mpira ali ndi chowunikira chapamwamba chapakompyuta kuti chiwunikire ndikuzindikira, kotero kulondola kwa makina a mpira ndikwambiri.
Monga momwe thupi la valavu likukhalira mofanana ndi zida za chitoliro, sipadzakhalanso kupanikizika kosagwirizana komanso kusinthika chifukwa cha chivomezi ndi galimoto yomwe ikudutsa pansi.Chitolirocho sichimva kukalamba.
Gulu la mphete yosindikizira limapangidwa ndi RPTFE yokhala ndi 25% Carbon(Carbon), yomwe imatsimikizira kuti palibe kutayikira (0%).
Direct m'manda kuwotcherera valavu mpira akhoza kukwiriridwa mwachindunji pansi popanda kufunika kumanga lalikulu valavu bwino.Ndi zitsime zazing'ono zokha zomwe zimayikidwa pansi kuti zisunge ndalama zomanga ndi nthawi yomanga kwambiri.
