Adjustable Non Return 0-2,5bar Valve for Conc Chemical (Kalrez/Viton)

The Adjustable Non-Return Valve is rated from 0 to 2.5 bar and is fitted with Viton seals. It is a precision flow-control component designed to prevent backflow of concentrated chemicals into upstream supply lines. Its adjustable cracking pressure allows hygiene engineers to set the valve’s opening threshold to match specific system operating pressures, ensuring reliable one-way flow across a wide range of operating conditions. The Viton seal provides excellent chemical compatibility with virtually all cleaning agents and sanitisers used in food-industry hygiene processes.
