Non valve isanzwe ni ubwoko bwa valve idafite ibipimo ngenderwaho bisobanutse. Imikorere yimiterere nubunini byashizweho byumwihariko ukurikije ibisabwa. Irashobora gushushanywa no guhindurwa mubwisanzure bitagize ingaruka kumikorere n'umutekano. Nyamara, inzira yo gutunganya iracyakurikiza ingingo zijyanye nigipimo cyigihugu.

Igishushanyo mbonera kitari cyiza kigomba gusuzuma gushyira mu gaciro no gushoboka muri byose. Usibye gushingira kumyumvire gakondo, igishushanyo gikenera ubushakashatsi bushya niterambere. Kubwibyo, muri rusange, hari intore mu nganda kugirango zirangize imirimo isa, kandi ba injeniyeri bazatanga ibishushanyo nyuma yo gushushanya.

Ubwoko bwimyanda idasanzwe igabanijwemo ibice byimyanda yimyanda (irembo ryikaramu na flap valve) hamwe nicyuma cya metallurgical (indege yikinyugunyugu ihumeka, irembo rya slide, valve ya goggle, valve isohora ivu, nibindi)
