NRV Non Return Valve – Adjustable 0.5-4bar – Viton

The Non-Return Valve is adjustable from 0.5 to 4 bar and fitted with Viton seals, making it a versatile backflow prevention device for chemical dosing and foam cleaning systems across a wide range of operating pressures in food and beverage production facilities. Its broad 0.5 to 4 bar adjustment range allows hygiene engineers to set the cracking pressure precisely to each installation’s requirements, ensuring reliable, one-way chemical flow under varying supply conditions. Viton (FKM) seals deliver excellent resistance to alkaline detergents, acidic cleaners, and sanitising agents, providing long service life and dependable sealing performance in chemically demanding applications. The adjustable design also reduces the need to stock multiple fixed-pressure valves for different systems, making this a versatile and cost-effective component choice.
