Pneumatisk betjent 2/2-vejs membranventil med kunststof-aktuator (type CLASSIC)
Type 2031 / Artikelnr. 347798
Produktbeskrivelse
Den eksternt styrede membranventil type 2031 består af en pneumatisk betjent stempelaktuator, en membran og et 2-vejs ventilhus. Den gennemtestede og robuste aktuator med plasthus sikrer brug under hygiejniske eller aggressive omgivelsesbetingelser. Det floweffektive ventilhus med minimalt dødrum giver mulighed for høje gennemstrømningsværdier og alsidige anvendelsesmuligheder. Ventilhus og membran fås i alle almindelige materialer og varianter. Aktuatoren har et kompakt autoklaverbart design (PPS-variant). Integreringen af automatiseringsenheder 8690/8691/8697 er mulig i alle udbygningstrin (kan eftermonteres). En eksplosionsbeskyttet ATEX/IECEx-enhedsvariant er tilgængelig. Huset til påsætning fås efter valg i plast eller rustfrit stål. Som standard forsynes aktuatoren med en integreret, optisk indikationsvisning, efter valg kan der monteres en min./maks. slagbegrænsning.
