Iivalvu zebhabhathane zinokwahlulwa zibe ziivalvu zebhabhathane ezisebenzisa umoya, iivalvu zebhabhathane zombane, iivalvu zebhabhathane ezenziwe ngesandla, njl. Ivalvu yebhabhathane yivalvu esebenzisa ipleyiti yebhabhathane ejikelezayo njengenxalenye yokuvula nokuvala kwaye ijikeleza ngesiqu sevalvu ukuvula, ukuvala nokulungisa indlela yolwelo. Ipleyiti yebhabhathane yevalvu yebhabhathane ifakwe kwicala lobubanzi bombhobho. Kwindlela yokujikeleza yomzimba wevalvu yebhabhathane, ipleyiti yebhabhathane efana nediski ijikeleza i-axis, kwaye i-engile yokujikeleza iphakathi kwe-0° kunye ne-90°. Xa ukujikeleza kufikelela kwi-90°, ivalvu ivulwa ngokupheleleyo. Ivalvu yebhabhathane, ekwabizwa ngokuba yi-flap valve, luhlobo lwevalvu elawulayo enesakhiwo esilula. Ingasetyenziselwa nokulawula imidiya yepayipi enoxinzelelo oluphantsi. Ivalvu yebhabhathane ibhekisa kuhlobo lwevalvu apho inxalenye yayo yokuvala (idiski okanye ipleyiti yebhabhathane) iyidiski, ejikeleza umngxuma wevalvu ukuze ivuleke kwaye ivale. Isetyenziselwa ikakhulu ukusika nokugoba umbhobho. Inxalenye yokuvula nokuvala ivalvu yebhabhathane yipleyiti yebhabhathane emilise okwediski, ejikeleza i-axis yayo emzimbeni wevalvu ukuze ifezekise injongo yokuvula nokuvala okanye ukulungisa. Ivalvu yebhabhathane idla ngokuba ngaphantsi kwama-90° ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo. Ivalvu yebhabhathane kunye nesiqu sebhabhathane azinawo amandla okuzitshixa. Ukuze ipleyiti yebhabhathane ibekwe, kufuneka kufakwe isixhobo sokunciphisa iigiya zezinambuzane kwisiqu sevalvu. Ukusetyenziswa kwesixhobo sokunciphisa iigiya zezinambuzane akunakwenza nje kuphela ukuba ipleyiti yebhabhathane ibe namandla okuzitshixa, kwenze ipleyiti yebhabhathane ime nakweyiphi na indawo, kodwa kukwaphucula nokusebenza kwevalvu. Ivalvu yebhabhathane yezimboni iphawulwa kukumelana nobushushu obuphezulu, uluhlu oluphezulu loxinzelelo olusebenzayo, ububanzi obukhulu bevalvu, umzimba wevalvu wenziwe ngentsimbi yekhabhoni, kwaye iringi yokutywina yepleyiti yevalvu isebenzisa iringi yesinyithi endaweni yeringi yerabha. Ivalvu yebhabhathane enkulu enobushushu obuphezulu yenziwe ngentsimbi yentsimbi, kwaye isetyenziselwa ikakhulu imibhobho yeflue kunye nemibhobho yegesi yemidiya yobushushu obuphezulu.

Iivalvu zebhabhathane zinokwahlulwa zibe ludidi lwepleyiti ye-offset, uhlobo lwepleyiti ethe nkqo, uhlobo lwepleyiti etyebileyo kunye nohlobo lwe-lever ngokwesakhiwo. Ngokwemo yokutywina, inokwahlulwa ibe ziintlobo ezimbini: uhlobo olutywiniweyo nohlobo olutywiniweyo oluqinileyo. Uhlobo lokutywina oluthambileyo ludla ngokusebenzisa itywina yerabha, kwaye uhlobo lokutywina oluqinileyo ludla ngokusebenzisa itywina yentsimbi. Ngokwemo yokuqhagamshela, inokwahlulwa ibe ludibaniso lweflange kunye nodibaniso lwe-wafer; ngokwemo yokutshintshela, inokwahlulwa ibe ludibaniso lwesandla, udluliselo lwegiya, umoya, i-hydraulic kunye nombane.
