Kwindlela yokwahlulahlula iivalvu ezingaqhelekanga, ukongeza kwiivalvu ezingaqhelekanga ezintathu, iivalvu ezingaqhelekanga ezimbini zisetyenziswa kakhulu. Ivalvu esebenza kakuhle (HPBV), iimpawu zayo: ubomi obude, amaxesha okutshintsha elebhu ukuya kuthi ga kwisigidi esinye.

Xa ithelekiswa nevalvu yebhabhathane esembindini, ivalvu yebhabhathane ephindwe kabini engaqhelekanga iyakwazi ukumelana noxinzelelo oluphezulu, iphila ixesha elide kwaye izinzile kakuhle.
I-HPBV isetyenziswa kakhulu kwiifayile zamanzi olwandle, kushishino lweekhemikhali, kwi-HVAC, kwiimeko zokubola, njl.
Okulandelayo liqela leevalvu zebhabhathane ezisebenza kakuhle ezithunyelwa eYurophu,iinkcukacha ezithile zezi zilandelayo;
