Umupirana plug ya valve nubwoko bumwe bwa valve, gusa igice cyayo cyo gufunga ni umupira, umupira uzenguruka umurongo wo hagati wumubiri wa valve kugirango ugere kumugaragaro, ufunze valve. Umupira wumupira mumuyoboro ukoreshwa cyane cyane mugukata, gukwirakwiza no guhindura icyerekezo cyogukoresha. Umupira wumupira ukoreshwa cyane mumyaka yashize nubwoko bushya bwa valve ball valve na plug valve nubwoko bumwe bwa valve, gusa igice cyayo cyo gufunga ni umupira, umupira uzengurutse umurongo wo hagati wumubiri wa valve kugirango uzunguruke kugirango ufungure kandi ufunge valve.

Umupiramu muyoboro ukoreshwa cyane cyane guca, gukwirakwiza no guhindura icyerekezo gitemba. Umupira wumupira nubwoko bushya bwa valve yakoreshejwe cyane mumyaka yashize. Ifite ibyiza bikurikira:

1. Kurwanya amazi ni bito, kandi coeffisente yayo yo kurwanya iringana niy'igice cy'imiyoboro y'uburebure bumwe.

2. Imiterere yoroshye, ingano nto, uburemere bworoshye.

3. Birakomeye kandi byizewe, ibikoresho byo gufunga umupira wumupira ukoreshwa cyane muri plastiki, gufunga neza, kandi byakoreshejwe cyane muri sisitemu ya vacuum.

4. Biroroshye gukora, gufungura no gufunga byihuse, kuva byuzuye kugeza byuzuye hafi igihe cyose kuzunguruka 90 °, byoroshye kugenzura kure.

5. Kubungabunga byoroshye, imipira ya valve iroroshye, impeta yo gufunga muri rusange irakora, gusenya no kuyisimbuza biroroshye.

6. Iyo ifunguye neza cyangwa ifunze byuzuye, hejuru yumupira wumupira hamwe nintebe ya valve bitandukanijwe hagati. Iyo imiyoboro inyuze, ntabwo bizatera isuri yubuso bwa kashe.

7. Birashobora gukoreshwa muburyo bunini kuva kuri ntoya kugeza kuri milimetero nkeya kugeza kuri metero nkeya, kuva mumyuka mwinshi kugeza kumuvuduko mwinshi urashobora gukoreshwa.

Umupirayakoreshejwe cyane muri peteroli, inganda zikora imiti, kubyara amashanyarazi, gukora impapuro, ingufu za atome, indege, roketi nandi mashami, ndetse nubuzima bwa buri munsi bwabantu.
