Amavalvu ebhabhathane angahlukaniswa ngamavalvu ebhabhathane asebenzisa umoya, amavalvu ebhabhathane kagesi, amavalvu ebhabhathane asetshenziswa ngesandla, njll. Ivalvu yebhabhathane iyivalvu esebenzisa ipuleti lebhabhathane eliyindilinga njengengxenye yokuvula nokuvala futhi ijikeleza ngesiqu sevalvu ukuvula, ukuvala nokulungisa indlela yoketshezi. Ipuleti lebhabhathane levalvu yebhabhathane lifakwe ohlangothini lobubanzi bepayipi. Endleleni eyindilinga yomzimba wevalvu yebhabhathane, ipuleti lebhabhathane elimise okwediski lijikeleza i-axis, kanti i-engeli yokujikeleza iphakathi kuka-0° no-90°. Lapho ukujikeleza kufinyelela ku-90°, ivalvu ivulwa ngokugcwele. Ivalvu yebhabhathane, ebizwa nangokuthi i-flap valve, uhlobo lwevalvu elawulayo enesakhiwo esilula. Ingasetshenziswa futhi ekulawuleni imidiya yepayipi enengcindezi ephansi. Ivalvu yebhabhathane ibhekisela ohlotsheni lwevalvu olunengxenye yokuvala (idiski noma ipuleti lebhabhathane) eyidiski, ejikeleza ishafti yevalvu ukuze ivuleke futhi ivale. Isetshenziswa kakhulu ukusika nokugoqa ipayipi. Ingxenye yokuvula nokuvala ivalvu yebhabhathane iyipuleti lebhabhathane elimise okwediski, elijikeleza i-axis yalo emzimbeni wevalvu ukuze kufezwe injongo yokuvula nokuvala noma ukulungisa. Ivalvu yebhabhathane ivame ukuba ngaphansi kwama-90° ukusuka ekuvulekeni ngokuphelele kuya ekuvalekeni ngokuphelele. Ivalvu yebhabhathane kanye nesiqu sebhabhathane azinawo amandla okuzikhiya. Ukuze kubekwe ipuleti lebhabhathane, kufanele kufakwe i-worm gear reducer esiqwini sevalvu. Ukusetshenziswa kwe-worm gear reducer akugcini nje ngokwenza ipuleti lebhabhathane libe nekhono lokuzikhiya, lenze ipuleti lebhabhathane lime kunoma yisiphi isikhundla, kodwa futhi kuthuthukise ukusebenza kwevalvu. Ivalvu yebhabhathane yezimboni ibonakala ngokumelana nokushisa okuphezulu, ububanzi bokucindezela obusebenzayo obuphezulu, ububanzi obukhulu bevalvu, umzimba wevalvu wenziwe ngensimbi yekhabhoni, kanti indandatho yokuvala yepuleti le-valve isebenzisa indandatho yensimbi esikhundleni sendandatho yerabha. Ivalvu yebhabhathane enkulu eshisa kakhulu yenziwe ngokushisela ipuleti lensimbi, futhi isetshenziselwa kakhulu imibhobho yomoya kanye namapayipi egesi e-media yokushisa okuphezulu.

Amavalvu e-Butterfly angahlukaniswa ngohlobo lwepuleti elingaphandle, uhlobo lwepuleti eliqondile, uhlobo lwepuleti elithambekele kanye nohlobo lwe-lever ngokwesakhiwo. Ngokwesimo sokuvala, lingahlukaniswa ngezinhlobo ezimbili: uhlobo oluvalwe ngokulinganayo nohlobo oluvalwe ngokuqinile. Uhlobo lokuvala oluthambile luvame ukusebenzisa uphawu lwendandatho yerabha, kanti uhlobo lokuvala oluqinile luvame ukusebenzisa uphawu lwendandatho yensimbi. Ngokwesimo sokuxhuma, lingahlukaniswa ngokuxhumeka kwe-flange kanye nokuxhumeka kwe-wafer; ngokwesimo sokudlulisa, lingahlukaniswa ngokudluliselwa ngesandla, kwegiya, kwemoya, kwe-hydraulic kanye nokwegesi.
