I-valve yemitha yegesi yezimboni iyisisetshenziswa esisetshenziselwa ukulawula ukuhamba kwegesi yezimboni, futhi ivame ukusetshenziswa ezinhlelweni zokulinganisa igesi yezimboni. Ama-valve wamamitha egesi yezimboni ngokuvamile anezimpawu zokumelana nezinga lokushisa eliphezulu, ukucindezela okuphezulu, ukumelana nokugqwala kanye nokusebenza kahle kokuvala ukuze kuhlangatshezwane nezidingo zezinhlelo zemitha yegesi yezimboni.

I-RKF-5 imitha yegesi yokuvala i-valve yokuvalaithuthukiswa yinkampani yethu. Kuyi-valve efakwe ngokukhethekile kumamitha egesi ezimbonini nezohwebo. Isetshenziselwa kakhulu ukulawula ukucisha kwegesi, futhi isikhathi sokushintsha singu-≤4.5s (DC3V). I-valve ithatha umdwebo oyingqayizivele wokuvala nokuma futhi inezici zokuthembeka okuphezulu nokulahlekelwa kwengcindezi encane. Ngesikhathi esifanayo, usayizi wayo omncane ungashintshwa ukuze ube namawashi ayisisekelo abakhiqizi abakhulu bewashi lesisekelo.
