Servem řízený 2/2-cestný membránový ventil
Type 6281 / Ident No. 248179
Product description
Ventil 6281 je servem řízený membránový ventil konstrukční řady S.EV. Pro správnou funkci ventilu je vždy potřebný minimální diferenční tlak. Podle aplikací jsou k dispozici různé materiály membrán a způsoby funkce. Standardní mosazné těleso splňuje všechny evropské požadavky pro pitnou vodu. Pro další trhy je k dispozici mosaz odolná proti odzinkování. Nabídka těles je doplněna nerezovou variantou. Magnetické cívky jsou olisovány chemicky vysoce odolným epoxidem. Pro snížení spotřeby energie mohou být všechny cívky dodány s elektronickým poklesem výkonu. Je možné vybavení ventilu ručním ovládáním pro jednoduchou údržbu a opravy. Ve spojení s konektorem DIN EN 17301-803 tvar A splňují ventily stupeň krytí IP65 – ve spojení s nerezovým tělesem splňují NEMA 4X.
