Kubireba imikorere yoroshye yo guca, imikorere yo gufunga valve mumashini nugukumira uburyo bwo gusohoka cyangwa kubuza ibintu byo hanze kwinjira imbere imbere bihujwe hagati yibice biri mu cyuho aho valve iherereye. . Abakoroni nibice bigize uruhare rwo gufunga byitwa kashe cyangwa ibyubatswe, byitwa kashe kubugufi. Ubuso buhuza na kashe kandi bugira uruhare mukudodo byitwa kashe.

Ubuso bwa kashe ya valve nigice cyibanze cya valve, kandi imiterere yacyo irashobora kugabanywa muri ubu bwoko, aribwo kumeneka hejuru yikimenyetso, kumeneka kwimpeta yikimenyetso, kumeneka kwikimenyetso kigwa kuzimya no kumeneka kubibazo byamahanga byashyizwe hagati yikimenyetso. Imwe mu miyoboro ikoreshwa cyane mu miyoboro n'ibikoresho ni uguhagarika urujya n'uruza. Kubwibyo, gukomera kwayo nikintu nyamukuru cyo kumenya niba kumeneka imbere bibaho. Ubuso bwa kashe ya valve igizwe mubusanzwe igizwe na kashe ebyiri, imwe kumubiri wa valve indi kuri disiki ya valve
