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.

• 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
