Bakeng sa lits'ebetso tsa khatello e phahameng le mocheso o phahameng, li-valve tsa liheke tsa tšepe tsa JLPV li nyane, li ka tšeptjoa ebile li nepahetse. Li-valve tsa ka ntle tsa screw le mofuta oa joko (OS & Y) tse nang le kutu e phahamang le lebili la letsoho le sa phahamang ke seo li-valve tsena li leng sona. Li-valve tsena li tlameha ho ba le bonne e tlanngoeng kapa e cheselitsoeng le bore e tletseng kapa e tloaelehileng. e loketseng ho kenngoa libakeng tse hloekisang, litsing tsa lik'hemik'hale, limela tsa petrochemical, mekhoa ea indasteri ea oli, kapa libakeng tse ling moo phallo ea phallo e hlokahalang ka lebaka la ho bola kapa khoholeho.
Ho na le mekhoa e 'meli e fapaneng ea bonnet bakeng sa li-valve tsa liheke tsa tšepe tsa JLPV. The Bolted Bonnet, lenonyeletso la monna le mosali le nang le spiral coiled gasket e entsoeng ka F316L le graphite, ke moralo oa pele. Ka kopo, li-gaskets tsa ring joint gaskets li fumaneha hape. Bonnet e cheselitsoeng ke moralo oa bobeli, 'me e na le mateano a khoele le a tiisitsoeng. Khokahano e cheselitsoeng ka botlalo e nang le matla a ho kenella ka botlalo e fumaneha ha o e kopa.
Mefuta e fapaneng ea moralo oa li-valve tsa tšepe tsa JLPV Forged ke ka tsela e latelang:
