I totonu o le lalolagi lavelave o vaega valve alamanuia, o le faʻamaoni ma le faʻamaoni o vaega taʻitasi e faia se sao taua i le faʻaogaina lelei ma le saogalemu. O le Sansheng Fluorine Plastics o lo'o tu i luma o lenei alamanuia, paionia fofo fou ma a tatou laina oloa faʻapitoa, e aofia ai le Keystone Sanitary Butterfly Valve Sealing Ring. O matou nofoa valve, faia mai le taupou PolyTetraFluoroEthylene (PTFE), faʻatulagaina le faʻataʻitaʻiga mo le lelei i le malo o le fluorocarbon - polymers faʻavae, ofoina atu vailaʻau e le mafaatusalia tetee ma le tumau.
O le maatulimanu o la matou oloa, le Keystone Sanitary Butterfly Valve Seling Ring, o loʻo faʻaalia ai le faʻataʻitaʻiga o le faʻainisinia saʻo ma le maualuga o meafaitino. Virgin PTFE, e ta'ua fo'i fa'alaua'itele o Teflon, e le na'o so'o se mea. O le tulaga auro mo le tete'e o vaila'au i le lalolagi palasitika, fa'amautinoaina o tatou nofoa alatoto e tetee atu i si'osi'omaga sili ona leaga e aunoa ma se fa'aletonu. O lenei filifiliga faaletino e le o soona fai; ose fa'ai'uga fa'apitoa e ofoina atu oloa e le gata ina fa'amalieina, ae sili atu i tulaga o alamanuia mo le tumau, fa'amaoni, ma le fa'atinoga. O nofoa va'a ta'itasi ua va'aia ma le toto'a ina ia fetaui ma valve butterfly e amata mai i le DN50 i le DN600, fa'amalieina i le lautele o alaleo o talosaga tau alamanuia. O le mea lea e le gata ina fegalegaleai ai le tatou Keystone Sanitary Butterfly Valve Valve Sealing Ring i auala eseese ae fa'alagolago fo'i i le lautele o le vevela. Pe o au fa'agaioiga e aofia ai sua maualuga-vevela po'o mana'omia ni vaega fa'amama malolosi, o matou nofoa valve PTFE e tula'i mai i le lu'itau. O la matou tautinoga i le lelei ma le faʻafouina o loʻo atagia i oloa uma matou te ofoina atu, o loʻo vaseina e lo matou faʻamaoni i le tausiga o le siosiomaga ma le tulaga faʻapitoa. Fa'atasi ai ma le Sansheng Fluorine Plastics, fa'amalosia au fa'agaioiga i vaega o le valve e folafola ai le leai o se li'o, sili atu le fa'atinoga, ma le umi e le mafaatusalia.

Zero Leakage PTFE Valve Nofo Butterfly Valve Vaega DN50 - DN600
Taupou PTFE (Polytetrafluoroethylene)
PTFE (Teflon) o le fluorocarbon faʻavae polymer ma e masani lava o le sili ona faʻamaʻi faʻamaʻi mai palasitika uma, aʻo faʻatumauina mea lelei faʻamalama ma eletise eletise. O le PTFE e iai foʻi le maualalo o le feteʻenaʻiga o lea e lelei mo le tele o faʻaoga maualalo.
O mea nei e le fa'aleaga ma talia e le FDA mo mea'ai. E ui lava o mea faʻainisinia o le PTFE e maualalo, faʻatusatusa i isi palasitika faʻainisinia, e tumau pea lona aoga i luga o le lautele o le vevela.
Va'aiga vevela: -38°C i le +230°C.
Lanu: paepae
Fa'aopoopo fa'asili: 0%
Parameter Laupapa:
| Mea | Talafeagai Temp. | Uiga |

O le pa'u nitrile e lelei lona lava - fa'alauteleina meatotino, abrasion tete'e ma hydrocarbon - mea e tete'e. E mafai ona faʻaaogaina e avea o se mea lautele mo vai, vacuum, acid, masima, alkali, gaʻo, suauu, pata, suauʻu hydraulic, glycol, ma isi. E le mafai ona faʻaaogaina i nofoaga e pei o le acetone, ketone, nitrate, ma fluorinated hydrocarbons. |
