Libliklappkasutatakse peamiselt vedelate, gaasiliste madala rõhuga suure läbimõõduga torujuhtmete jaoks. See sobib olukordadeks, kus rõhukadude nõue pole kõrge, on vaja vooluhulga reguleerimist ning avamis- ja sulgemisnõuded on kiired; Üldiselt on temperatuur alla 300 ° C ja rõhk alla 40 kg). Söödet kasutatakse tavaliselt vee ja gaasi jaoks ning sööda vajadus pole suur. Kasutada võib ka graanulit.

1) Meedia, mislibliklapptransportida ja kontrollida on vesi, kondensaat, tsirkuleeriv vesi, kanalisatsioon, merevesi, õhk, gaas, vedel maagaas, kuiv pulber, läga, puuvilja läga ja segu hõljuvate ainetega.
2) Tavaliselt on drosselimisel, reguleerimisel ja mudakeskkonnas vaja lühikest konstruktsiooni pikkust ning kiiret avanemis- ja sulgemiskiirust (1/4 pööret). Madalrõhulüliti (madal rõhu erinevus),libliklappon soovitatav.
3) Libliklapp can be used in double position adjustment, necking channel, low noise, cavitation and gasification, a small amount of leakage to the atmosphere and abrasive medium.
4) When the libliklapp is used under special working conditions, such as throttling regulation, strict sealing requirement, severe wear and low temperature (cryogenic), the special libliklapp with special designed metal sealing belt regulating device, tri eccentric or Bi eccentric, shall be used.
5) Soft seal eccentric libliklapp is suitable for bidirectional opening and closing and adjustment of ventilation and dust removal pipeline, and is widely used in gas pipeline and water channel of metallurgy, light industry, electric power and petrochemical system.
6) Metal to metal wire sealed double eccentric libliklapp is suitable for urban heating, gas supply, water supply and other gas, oil, acid and alkali pipelines, as a regulating and throttling device.
7) Metal to metal face sealed triple eccentric libliklapp is not only used as program control valve of large PSA gas separation unit, but also widely used in petroleum, petrochemical, chemical, metallurgical, electric power and other fields. It is a good substitute for gate valve and stop valve.

MST libliklapp is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil, various acid and alkali and other pipelines which require complete sealing, zero leakage in gas test, high service lie and working temperature from - 10 ℃ to 150 ℃.
