Plánujem inštalovať tento poistný ventil KB20 DUCO na zásobníkový ohrievač teplej vody s objemom 150 litrov. Vstupný rad ohrievača má závit 3/4", no výstup poistného ventilu je 1" – musím na to pripraviť špeciálny odpad, alebo to nejako môžem redukovať priamo pri ventile?

Ventil IVAR.PV KB20 DUCO má vstupný závit 3/4" F, čo plne zodpovedá bežnému pripojeniu zásobníkových ohrievačov – napojíte ho teda priamo bez redukcie na vstupnej strane. Výstupný závit 1" F je dimenzovaný na odvádzanie väčšieho množstva vody pri otvorení ventilu, pričom na odpadovú stranu odporúčame osadiť príslušnú odpadovú rúrku (prípadne s redukciou na bežný DN25 odpad), ktorá musí byť vedená voľne do viditeľného miesta alebo do podlahovej vpuste – nikdy nesmie byť zaslepená. Nastavená hodnota 7 bar je pre bežné tlakové pomery v bytových a rodinných domoch štandardná, no vždy si overte, aký maximálny pracovný tlak udáva výrobca vášho ohrievača – ten nesmie hodnotu ventilu presahovať. Hodnota Kv 0,580 zaručuje dostatočný prietok pri aktivácii ventilu pre zásobníky do bežných domácich objemov vrátane vašich 150 litrov. V prípade potreby nájdete v našej ponuke aj súvisiace montážne kusy a vypúšťacie sety pre zásobníkové ohrievače.
