Duo Valve – Combination Non-Return Isolating Valve
Available Variants: 12mm to 20mm
The Duo Valve is a compact, high-performance solution that combines two critical plumbing functions in one unit: non-return (check) valve and isolating valve. Designed specifically for the installation of pressurised water heaters, this valve ensures efficient system protection while simplifying the installation process.
Its one-piece design eliminates the need for separate valves and fittings, reducing the potential for leaks, installation errors, and unnecessary maintenance. The non-return component is tamper-proof, offering added safety, while the isolating feature provides convenient shut-off control.

- Leak Reduction: Fewer joins mean reduced chances of leaks or connection faults
- Tamper-Proof: Secure non-return valve prevents backflow without risk of tampering
- Optional Model: NRI50S 15mm Trio Valve version includes an integrated line strainer
- Orientation Flexibility: Functions effectively when installed horizontally or vertically
- Durable and Safe: Made from dezincification-resistant (DZR) brass
- Standards Approved: Complies with Australian Standards for potable water supply
Applications:
- Installation of electric or gas pressurised hot water systems
- General residential and commercial potable water systems
