Frequently asked questions
Kokia pavara tinka VVG44.20-6.3?
Tipiškai Siemens SAS31.03 (300 N, 30 s) mažoms sistemoms arba SAX31.03 (800 N) didesniems Δp.
Ar tinka DHW (KVR) grandinei?
Taip. VVG44 serija atitinka geriamojo vandens sistemų reikalavimus (bronza + SS sėdynė).
Ar galima naudoti glikolio mišinius?
Taip, iki 50 % etilenglikolio/propilenglikolio su tinkamais inhibitoriais.
Kuo skiriasi VVG44 nuo VVG549?
VVG44 — PN 16, bendriems ŠVOK kontūrams. VVG549 — PN 25, spaudimui atsparesnis (aukštybiniai pastatai, dideli komerciniai punktai).
