Mabili a matsoho bakeng sa li-valveke likarolo tsa bohlokoa lits'ebetsong tse fapaneng tsa indasteri, tse sebetsang karolo ea bohlokoa taolong ea phallo ea maro ka har'a lipeipi. Lisebelisoa tsena-tse sebelisoang ka letsoho li na le karolo e kholo ho netefatseng hore ts'ebetso e sebetsa hantle, e bolokehile, le ho laola liindasteri tse fapaneng.
Liindastering tse kang limela tsa lik'hemik'hale, tse hloekisang, le liteishene tsa motlakase, mabili a matsoho a li-valve a sebelisoa ho laola motsamao oa metsi le likhase ka liphaephe. Ka mohlala, lifemeng tsa lik'hemik'hale, mabili ana a sebelisoa ho laola phallo ea lik'hemik'hale tse fapaneng, ho netefatsa hore ho na le taolo e nepahetseng holim'a mekhoa ea tlhahiso. Ka mokhoa o ts'oanang, litsing tsa ho hloekisoa, mabili a matsoho a li-valve a thusa ho laola phallo ea oli e tala le lihlahisoa tsa peterole, ho thusa ho sebetsa hantle le ho thibela likotsi tse ka bang teng. Ho feta moo, liteisheneng tsa motlakase, mabili a matsoho a li-valve a sebelisoa ho laola phallo ea mouoane, metsi le maro a mang ka har'a li-boilers le liphaephe, ho netefatsa ts'ebetso e nepahetseng le polokeho tlhahisong ea motlakase.
Moralo oa li-handwheels bakeng sa li-valve o bonolo empa o sebetsa hantle, o lumella ho sebetsa habonolo ke basebelisi. Ka ho potoloha lebili la letsoho, valve e ka buloa kapa ea koaloa, kahoo e laola phallo ea metsi ka har'a phaephe. Moralo ona o hlakileng o netefatsa ho feto-fetoha ha maemo, bonolo, le karabelo e potlakileng ho lokisa sekhahla sa phallo ea mokelikeli ho latela litlhoko tsa ts'ebetso.
Ho feta moo, mabili a matsoho a li-valve a hahiloe ka-masebelisoa a tšepe a boleng bo holimo, a fanang ka nako e telele, a ts'epahala, le ho mamella ho bola. Sena se netefatsa botsitso le tshebetso ya nako e telele-, se fokotsa kotsi ya ho hloleha ha disebediswa le ho se sebetse ha disebediswa tsa indasteri. Ho feta moo, mabili a matsoho a li-valve a etselitsoe ho fana ka ts'ebetso e phahameng ea ho tiisa, ho thibela ka nepo ho tsoa ha mokelikeli le ho boloka botsitso ba sistimi ea liphaephe.
Qetellong, li-handwheels tsa li-valve li phetha karolo ea bohlokoa ho thusa ho laola le ho laola metsi ka mokhoa o nepahetseng lits'ebetsong tsa indasteri. Ho ba bonolo, ho ts'epahala, le ho tiea ha tsona ho li etsa likarolo tsa bohlokoa ho netefatsa ts'ebetso e sebetsang hantle, polokeho le taolo liindastering tse fapaneng.
