Okokuqala: i-valve handwheel diameters futhi amandla alinganiselwe, futhi abanye babona ububanzi isondo elincane 300 lapho abantu abathathu noma abane ukusebenza kulula ukulimaza, ngakho kumelwe sinake amamitha valve handwheel esingaphansi 320mm yilapho umuntu oyedwa operation.
Okwesibili: i-valve handwheel esesimweni esivamile, isimo sesimo sesondo lesandla singabuye sibe ama-valve ethu ayafana, ukusebenza kwe-valve handwheel kufanele kuhambisane newashi eduze newashi kufanele kuvuleke.
Okwesithathu: isondo le-valve elenziwe ngosayizi liyasetshenziswa, ngakho-ke kwesinye isikhathi siboleka okunye ukuhlaselwa ukuze sivule futhi sivale ama-valve, okubaluleke kakhulu ukugcina imithetho yethu. Okubushelelezi okuhle kakhulu ukuze ungalimazi ama-valve seal.
