Medprirobnični protipovratni ventil iz nerjavnega jekla BRA.06.623 brez vzmeti – DN 250, L = 38 mm
Koda: I06623250Podroben opis izdelka
Protipovratni ventil za utesnjen prostor
Ventil BRA.06.623 se vgradi med prirobnice cevovoda DN 250 (PN 6, PN 10, PN 16 in ANSI 150), kjer zavzame le 38 mm. Primeren je za ogrevanje in klimatizacijo (HVAC), vodovodna omrežja, stisnjen zrak, olja in ogljikovodike ter kemično in živilsko industrijo; prenese vodo z do 50 % glikolov in ima atest za pitno vodo. Za paro ni namenjen.
Izvedba
- ohišje, disk in plošča iz nerjavnega jekla ASTM A351 CF8M
- brez vzmeti – disk se zapre zaradi povratnega toka, najmanjši protitlak za zaprtje 0,3 bar
- tesnilni O-obroč iz PTFE – po navedbah proizvajalca pri vgradnji ni potrebno dodatno tesnilo
- centrirni profil, pozicionirna odprtina in transportno uho olajšajo vgradnjo
- zaobljen disk z omejilom ob steni cevi za največje odprtje in majhno tlačno izgubo, Kv 1670 m³/h
- masa 12,4 kg
Tlak, temperatura in vgradnja
Za vodo in nenevarne tekočine je največji tlak 25 bar, za nenevarne pline pri DN 250 16 bar; ventil ni namenjen nevarnim plinom. Temperaturno območje tesnila PTFE je od -20 do +200 °C, dovoljeni tlak pa z naraščanjem temperature pada. Ventil je enosmeren – vgradi se v smeri puščice na ohišju, v raven odsek cevovoda čim dlje od kolen, lokov in črpalk. Vijake je treba zategovati postopoma navzkrižno; razstavljanje in vzdrževanje pod tlakom nista dovoljena. Če potrebujete vgradnjo v poljubnem položaju, izberite izvedbo z vzmetjo BRA.M6.623 PR (koda M6623250).

Pogosta vprašanja
Ali je ventil brez vzmeti mogoče vgraditi v navpični cevovod?
Tehnični list dovoljuje vodoravno in navpično vgradnjo, najmanjši odpiralni tlak pa je odvisen od dimenzije in položaja vgradnje. Če potrebujete povsem prost položaj, izberite izvedbo z vzmetjo BRA.M6.623 PR.
Med katere prirobnice se prilega ventil DN 250?
Centrirni profil omogoča vgradnjo med prirobnice PN 6, PN 10 in PN 16 ter ANSI 150. Ventil se vstavi med prirobnice in stisne z vijaki prirobnic.
Ali je ventil primeren za sistem z glikolom?
Da, proizvajalec ga navaja za vodo z do 50 % glikolov. Ni primeren za paro in nevarne pline.
Kam v cevovod namestiti ventil?
V raven odsek čim dlje od kolen, lokov in obtočnih črpalk, da ob ventilu ne nastajajo turbulence.
