Kontraventiler

Vores kontraventiler beskytter slanger og vakuumsystemer mod tilbagestrømning, når trykket falder i systemet. Tætningssystemet eliminerer tilbagestrømning og hjælper med at forhindre forurening eller skader opstrøms. Disse ventiler er kompatible med en bred vifte af systemer, alle med forskellige specifikke niveauer ved håndtering af de tre primære trykværdier: åbningstryk, maksimalt tryk og det skabte modtryk. Holdbart stål eller plast anvendes i alle designs og skaber et kvalitetsprodukt, der forbliver pålideligt i mange år uden behov for udskiftning.
