I-valve core ifakwe emgodini wangaphakathi wengxenye engenhla ye-inner tube valve nozzle futhi iyi-valve enendlela eyodwa yokugcina uphawu. Faka i-valve core ukuze ijike kancane kancane, ayikwazi ukuqina kakhulu (akukho ukuvuza okungenzeka), ukuze ugweme i-thread buckle ye-valve core, ukwehluleka kwentwasahlobo, ukulahlekelwa yi-raber gasket yokuvala; Ngesikhathi esifanayo naka umlomo we-valve kanye nemisebenzi ye-valve core tappet flush, kulula ukukala i-barometer kanye ne-valve cap egqokwayo. Ngaphambi kokuvula, i-valve nozzle (kufaka phakathi i-valve core) kufanele isulwe kahle ukuze kuvinjelwe ukungcola ukungena epayipini langaphakathi. Lapho ivuthwa, i-valve core akufanele ikhishwe noma ikhululeke, njengoba ivame ukuvuthwa futhi ivuthwe, i-raber sealing ring izolahlekelwa kancane kancane umphumela wayo. Uma ulinganisa umfutho womoya, i-barometer kufanele ixhumane kakhulu ne-valve ye-core core valve, ungaphoqeleli kakhulu, ukuze ugweme umonakalo emshinini, ngemva kokugcwalisa kufanele uhlole ukuthi i-valve iyavuza yini emoyeni, uma kutholakala ukuvuza, kufanele ilungiswe noma ishintshwe izingxenye ezintsha ngesikhathi esifanele, ungafaki izikulufo ezinzima, ukuvimbela ukuphuka kwe-core valve noma ngesikhathi esizayo kube nzima ukuyisusa. Kumelwe ugcizelele ukugqoka yonke i-valve cap, futhi uqinise ngokuthembekile ukuvimbela uthuli, ukungcola emlonyeni, okubangela ukuvaleka nokugqwala, ukuze ukwehluleka kwentwasahlobo kubangele ukuvuza komoya okuhamba kancane.
