Imashini zubuye zubushinwa
kwibanda ku musaruro ureremba wa valve.Igishushanyo kireremba bisobanura impeta ebyiri zicaro zikoreshwa mugushigikira umupira mubwoko bwimipira ireremba.Igishushanyo gitera umupira kureremba cyangwa kugenda mucyerekezo cyimpeta yintebe hejuru.Igishushanyo kibereye ubunini buto hamwe numuvuduko muke wumupira.
Umupira ukomeye ukorwa muburyo bwo guterana cyangwa guhimba.Umupira ukomeye mubisanzwe ufatwa nkigisubizo cyiza cyubuzima.Kandi imipira ikomeye ikoreshwa cyane cyane mubihe byumuvuduko mwinshi.
Umupira wubusa ukorwa nicyuma gisudira icyuma cyangwa ibyuma bidafite ingese.Umupira wuzuye ugabanya umutwaro wubuso bwa sphericale hamwe nintebe ya valve kubera uburemere bwacyo bworoshye, bufasha kongera igihe cyumurimo wintebe ya valve.
Umupira uri muri trunnion ushyizwe kumupira wumupira ntushobora kugenda kuko umupira wumupira wa trunnion ufite urundi rubuto hepfo kugirango ushireho umwanya wumupira.Imipira yubwoko bwa trunnion ikoreshwa cyane cyane mubihe byumuvuduko mwinshi hamwe nubunini bunini bwumupira.
