Servostyrt 2/2-veis membran magnetventil
Type 6281 / Artikkelnr. 241036
Artikkelbeskrivelse
Ventilen 6281 er en servostyrt membranventil i serien S.EV. For at ventilen skal fungere riktig er det alltid nødvendig med et minimumsdifferansetrykk. Avhengig av applikasjonene er forskjellige membraner og virkemåter tilgjengelige. Standard messinghus oppfyller alle europeiske normer mht. drikkevannskrav. For andre markeder finnes avsinkningsstabil messing. Hus kommer i tillegg i en syrefast variant. Kjemisk høystabil epoksy presses på magnetspolene. For å redusere energibehovet kan alle spoler leveres med en elektronisk effektredusering. Ventilen kan utstyres med en manuell betjening for enkelt vedlikehold og igangkjøring. Sammen med en plugg i henhold til DIN EN 17301-803 form A oppfyller ventilene beskyttelsesart IP65 – i forbindelse med et edelstålhus NEMA 4X.
