Zero Leakage PTFE Valve Seat Butterfly Valve Parts DN50 - DN600
PTFE (Polytetrafluoroethylene)
PTFE (Teflon) ke polymer e thehiloeng ho fluorocarbon 'me ha e le hantle ke eona e hanyetsanang le lik'hemik'hale ho feta lipolasetiki tsohle, ha e ntse e boloka thepa e ntle ea mocheso le motlakase. PTFE e boetse e na le coefficient e tlase ea khohlano kahoo e loketse lits'ebetso tse ngata tse tlase tsa torque.
Thepa ena ha e na - e silafatsa ebile e amoheloa ke FDA bakeng sa lits'ebetso tsa lijo. Le hoja thepa ea mechine ea PTFE e tlaase, ha e bapisoa le lipolasetiki tse ling tse entsoeng ka boenjiniere, thepa ea eona e lula e le molemo ho feta mocheso o pharaletseng.
Sebaka sa mocheso: -38°C ho ea ho +230°C.
'Mala: bosoeu
Torque adder: 0%

Melemo:
PTFE e emetse PolyTetraFluoroEthylene, e leng lentsoe la lik'hemik'hale bakeng sa polymer (CF2)n.
Polytetrafluoroethylene (PTFE) ke setho sa thermoplastic sa lelapa la fluoropolymer la polasetiki 'me se na le coefficient e tlase ea likhohlano, thepa e ntle ea ho itšireletsa.
PTFE ha e sebetse ka lik'hemik'hale ho lintho tse ngata. E boetse e khona ho mamella lits'ebetso tsa mocheso o phahameng mme e tsebahala ka thepa ea eona ea anti- stick.
Ho khetha le tokelo ya setulo reng lintho tse bonahalang hangata ke qeto e phephetsang ka ho fetisisa ka Balofo ea Ball Khetho. Ho thusa bareki ba rona nakong ea ts'ebetso ena, re ikemiselitse ho fana ka tlhahisoleseling mabapi le kopo ea bareki.
Litulo tsa li-valve tsa PTFE tse hlahisoang ke US li sebelisoa haholo ka masela, seteishene sa matla, petrochemical, futhumatsang le sehatsetsing, meriana, kaho ea likepe, tšepe, indasteri e bobebe, ts'ireletso ea tikoloho, indasteri ea pampiri, indasteri ea tsoekere, moea o hatelitsoeng le likarolo tse ling.
Ts'ebetso ea sehlahisoa: ho hanyetsa mocheso o phahameng, ho hanyetsa acid e ntle le alkali le ho hanyetsa oli; e nang le mamello e ntle, e tiileng le e tšoarellang ntle le ho lutla.
