I-valve ye-butterfly yokungenisa umoya kagesi isetshenziswa ngokukhethekile kuzo zonke izinhlobo zomoya, kufaka phakathi igesi yothuli, igesi yokushisa okuphezulu kanye namanye amapayipi, njengokulawula ukugeleza kwegesi noma ukuvala, futhi kukhethwa izinto ezahlukene ukuze kuhlangatshezwane namazinga okushisa ahlukene aphakathi nendawo aphansi, aphakathi nendawo kanye naphezulu, kanye nabezindaba ezigqwalisayo. Ngokuvamile, izinga lokushisa liphakathi kuka-20 ~ 425 ℃, kanti ingcindezi ingaphansi kuka-0.6MPa. Inezinzuzo ze-torque encane yokusebenza kanye nokusebenza okulula, impilo yesevisi ende.

I-valve kagesi elawula ukungenisa umoya ingasetshenziswa ngokufaka isignali yokulawula (4 ~ 20mADC noma 1 ~ 5VDC) kanye nokunikezwa kwamandla afanele ukuhlangabezana nezidingo zokusebenza kwephayiphi. I-valve ye-ventilation butterfly isebenzisa isakhiwo esisha se-central line type disc plate kanye ne-short structure steel plate welding, enezici zesakhiwo esiqinile, isisindo esincane, ukufakwa okulula, ukumelana nokugeleza okuncane, ivolumu enkulu yokugeleza kanye nokusebenza okulula. Isetshenziswa kabanzi ezintweni zokwakha, i-metallurgy, izimoto, amandla kagesi, ukungenisa umoya, ubunjiniyela bokuvikela imvelo kanye neminye imboni.
