Maualuluga-Uulelei Bray PTFE+EPDM Butterfly Valve Liner
I le lalolagi o faʻaoga valve alamanuia, o le manaʻoga mo mea e ofoina atu uma le faʻaogaina o vailaʻau faʻapitoa ma le faʻatuatuaina o le faʻatinoga i lalo ole vevela eseese e le mafai ona faʻateleina. I le Sansheng Fluorine Plastics, matou te malamalama i nei manaʻoga taua ma e mitamita e faʻafeiloaʻi a matou mea sili ona lelei Bray PTFE + EPDM butterfly valve liners. Fuafuaina e faʻafeiloaʻi i le tele o faʻaoga faʻapisinisi, mai le DN50 i le DN600, o matou nofoa valve ua faʻainisinia mo le leai o se leakage, faʻamautinoaina le lelei o le gaioiga ma le saogalemu.
O a matou nofoa valve e faʻapipiʻiina mai le Virgin PTFE (Polytetrafluoroethylene), o se mea e taʻutaʻua ona o lona tetee atu i vailaʻau. O lenei uiga, tu'ufa'atasia ma le fetuutuuna'i ma le maufetuuna'i o le EPDM, ua avea ai a tatou Bray PTFE + EPDM butterfly valve liners o se filifiliga e le mafaatusalia mo faiga e mana'omia ai fofo fa'amaufa'ailoga tumau ma fa'atuatuaina. PTFE, ua lauiloa foi o Teflon, o se fluorocarbon - polymer faavae e tu e pei o le tumutumu o mea palasitisi, ofoina atu le vevela ma le eletise insulation meatotino, faatasi ai ma lona tetee le mafaatusalia i corrosive chemicals.Designed e tetee atu i le faigata o siosiomaga tau alamanuia, lo tatou Bray. PTFE + EPDM butterfly valve liners folafola le umi ma le faatinoga. O le tulaga ese le tumau o lenei oloa ma le le mautonu o vailaʻau e maua ai se tupe maua taua i luga o tupe teufaafaigaluega, faʻaitiitia ai le manaʻoga mo le sui soo ma le tausiga. Lelei mo le lautele o alaleo o talosaga, mai le gaosiga o vailaʻau i togafitiga vai, o matou nofoa valve e ofoina atu le fetaui lelei mo valve butterfly, faʻamautinoa le tapunia ma le saʻo lelei o le tafe. Faatasi ai ma le tautinoga a le Sansheng Fluorine Plastics i le lelei ma le faʻafouina, faʻamalosia au faʻaogaina i la matou vaʻavaʻa vaʻavaʻa Bray PTFE + EPDM ma iloa le faʻaogaina lelei ma le faʻamaoni.

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.

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. |
