EPDM Rubber Seat Ductile Iron Wafer Butterfly Valve

Tulaga lelei ole Butterfly Valve Ole pepe ole valve e tutusa ma le polo ae sili atu ona lelei. E tatala ma tapuni vave lava pe a fa'agaoioi i le pneumatically. O le tisiketi e mama atu nai lo le polo, ma o valve e manaʻomia le itiiti ifo o le lagolago faʻavae nai lo le polo valve e tutusa le lautele. O valve butterfly e matua sa'o lelei, lea e fa'amanuiaina ai i mea tau pisinisi. E matua fa'atuatuaina ma e mana'omia sina tausiga itiiti. 1. Kiina/tape faigofie ma vave ma itiiti le malosi. Fa'aitiitia le vai fa'asao ma e mafai ona fa'agaioia soo. 2. Faiga faigofie, laʻititi laʻititi ma pupuu faʻasaga i foliga, lea e talafeagai mo vaʻa lapoa lapoa. 3. E mafai ona faʻaaogaina mo le faʻasalalauina o palapala, faʻaitiitia le suavai o loʻo teuina i avanoa o paipa. 4. Soifua tautua umi. Tu'u i le su'ega o le fiasefulu afe o galuega tatala/tapuni. 5. Butterfly valves e sili ona lelei le faʻatinoga o tulafono faatonutonu. 6. Laiti torque. O le mamafa i luga o disks i itu e lua o le spindle e toetoe lava tutusa, ma mafua ai le faʻafeagai torque. O le mea lea, e mafai ona tatalaina alatoto ma le malosi itiiti. 7. Fa'amaufa'ailoga foliga e masani ona fa'aogaina i le pa'u po'o le palasitika. O lea la e mafai ona faʻamaufaʻailogaina ia valve butterfly i lalo o le mamafa maualalo. galue mamafa PN10, PN16 su'ega fa'amalosi atigi: 1.5 taimi fa'amauina pressureseat: 1.1 taimi fa'amauina mamafa galuega vevela -10 °C i le 80°C (NBR) -10 °C i le 120°C (EPDM) talafeagai vai ala o faasalalauga, suauu ma vaega kasa mea tino lafo uʻamea, uʻamea ductile, nofoa EPDM, NBR, VITON, PTFE tisiketi nickel uʻamea ductile, AI apamemea, uamea uamea ogalaau carbon uamea, uamea uʻamea bushing PTFE "O" mama PTFE pine uamea uamea ki uamea Design Standard EN 593 , MSS SP67 API 609 BS5155 Asiasiga & Su'ega API 598 ISO 5208 EN 12266 Fa'ai'uga Tulaga ANSI B16.1 CL. 125LB & B16.5 CL. 150LBAS 2129 Laupapa D & E BS 10 Laupapa D & E DIN 2501 PN6, PN10 & PN16 EN 1092 PN6, PN10 & PN16 ISO 2531 PN6, PN10 & PN16 ISO 7005 PN6, PN60K1 10K MSS SP44 CL. 150LB AWWAC207 SABS 1123 Laulau 1000/3 & Laulau 1600/3 Fa'asagaga ISO 5752 , EN 558 , MSS SP67 ma API 609 DIN3202 Top Flange ISO 5211 Oloa Fa'amatalaga Fa'agasolo Talosaga
