The Stefani 20mm Dual Check Valve is engineered to protect against cross-contamination by preventing non-potable water from entering your clean drinking supply. Featuring two spring-loaded check valves, it stays securely closed until water is required downstream.
In the event of reverse flow, the valves shut immediately to prevent backflow.
Ideal for low-hazard applications such as meter connections in residential settings.
Approved to AS 2845.1 standards for backflow prevention.
