Li-valve tsa ho laola phallophetha karolo ea bohlokoa ho netefatsa ts'ebetso e nepahetseng le e bolokehileng ea lits'ebetso tse fapaneng ka har'a lekala la eneji. Li-valve tsena li laola phallo ea maro a kang metsi, mouoane, le khase ea tlhaho, ho pholletsa le mefuta e mengata ea ts'ebeliso, ho kenyeletsoa ho fehla motlakase, tlhahiso ea oli le khase, le ho hloekisoa. Ka ho ntlafatsa taolo ea phallo, li-valve tsena li kenya letsoho ho bolokeng matla a bohlokoa, ho fokotsa mesi, le ho ntlafatsa botsitso ba ts'ebetso.
Litsing tsa motlakase, li-valve tsa taolo ea phallo ke likarolo tsa bohlokoa lits'ebetsong tse fapaneng, ho kenyeletsoa li-turbine tsa mouoane, litsamaiso tsa metsi a phepelo le sistimi ea metsi a pholileng. Taolo e nepahetseng ea phallo e bohlokoa bakeng sa ho boloka khatello e nepahetseng ea mouoane le mocheso, ho netefatsa ts'ebetso e nepahetseng ea turbine, le ho thibela tšenyo ea lisebelisoa. Ka ho sebelisa li-valve tsa taolo ea phallo e tsoetseng pele, limela tsa motlakase li ka fihlela ntlafatso e hlokomelehang ea ts'ebeliso ea matla, e lebisang ho fokotseng tšebeliso ea mafura le litšenyehelo tse tlase tsa ts'ebetso.
Setsi sa motlakase se seholo sa United States se ntlafalitse tsamaiso ea sona ea ho laola turbine ea mouoane ka li-valve tse bohlale tse laolang phallo. Li-valve tsena, tse nang le li-sensor tse tsoetseng pele le li-actuator, li fane ka tlhahlobo ea nako ea nnete le litokiso tse nepahetseng ho phallo ea mouoane. Ka lebaka leo, setsi sa motlakase se hlokometse keketseho ea 2% ea ts'ebetso ea turbine, e fetolelang polokelong ea selemo le selemo ea $ 1 milione.
Indastering ea oli le khase, li-valve tsa ho laola phallo li phetha karolo ea bohlokoa ho laola phallo ea metsi nakong ea tlhahiso, ea lipalangoang le ea ho sebetsa. Ho ntlafatsa taolo ea phallo ho thusa ho eketsa tlhahiso ea li-wellhead, ho fokotsa tahlehelo ea khatello liphaepheng, le ho ntlafatsa katleho ea karohano litsing tsa ts'ebetso. Ka ho fokotsa tšebeliso ea matla le ho eketsa chai ea lihlahisoa, li-valve tsa taolo ea phallo li kenya letsoho molemong oa kakaretso oa ts'ebetso ea oli le khase.
Mokhanni oa sebaka sa oli Bochabela bo Hare o kentse tšebetsong lenaneo le felletseng la taolo ea phallo ho pholletsa le liliba tsa eona tsa tlhahiso. Ka ho sebelisa li-valve tsa ho laola phallo e sebetsang hantle le mekhoa e tsoetseng pele ea ho laola, mosebeletsi o ile a finyella keketseho ea 5% ea tlhahiso ea li-wellhead, e leng se ileng sa fella ka libarele tse eketsehileng tsa 10,000 tsa oli ka letsatsi.
Litsing tsa ho hloekisa le ho sebetsa, li-valve tsa taolo ea phallo li bohlokoa bakeng sa ho boloka taolo e nepahetseng holim'a phallo ea mokelikeli lits'ebetsong tse fapaneng, ho kenyelletsa le distillation, cracking, le ho kopanya. Taolo e nepahetseng ya phallo e netefatsa boleng bo nepahetseng ba sehlahiswa, e fokotsa tshebediso ya matla, mme e thibela ho qhalana ho kotsi le ho dutla. Ka ho kenya letsoho ts'ebetsong e sebetsang hantle le e lumellanang le tikoloho, li-valve tsa ho laola phallo li phetha karolo ea bohlokoa ho ts'ebetsong ea indasteri ea ho hloekisa le ho e lokisa.
Setsi sa tlhoekiso Europe se ile sa kenya tšebetsong morero oa ho nkela li-valve tsa taolo ea botsofali sebaka ka mefuta ea sejoale-joale, e baballang matla. Li-valve tse ncha li fane ka taolo e matla ea ho phalla le ho fokotsa tahlehelo ea khatello, e leng se lebisang ho fokotseha ha 10% ea tšebeliso ea matla. Phokotso ena ea tšebeliso ea matla e fetoletsoeng e le phokotso e kholo ea likhase tse futhumatsang lefatše, e leng se bontšang melemo ea tikoloho ea theknoloji e tsoetseng pele ea ho laola phallo.
Li-valve tse laolang phallo ha se likaroloana tsa mochini feela; ke tsona tse nolofalletsang ts'ebetso le ts'ebetso ea ts'ebetso lekaleng la eneji. Ka ho ntlafatsa taolo ea phallo, li-valve tsena li kenya letsoho ho fokotseng tšebeliso ea matla, ho fokotsa likhase, le ho ntlafatsa botsitso ba ts'ebetso. Ha lekala la eneji le ntse le fetohela bokamosong bo hlwekileng le bo tswelang pele, di-valve tsa taolo ya phallo di tla tswelapele ho bapala karolo ya bohlokwa ho fihlelleng maikemisetso ana.
