DZR Brass Double Check Valve PRODUCT CODE - ART 36

DZR Brass Double Check Valves provide a robust, corrosion‑resistant solution for preventing backflow in potable‑water and general plumbing systems. Manufactured from dezincification‑resistant (DZR) brass, they’re specifically designed for environments where standard brass may suffer from corrosion, ensuring long‑term reliability and compliance with water‑supply regulations.

The double‑check design features two independent non‑return mechanisms, offering a higher level of protection against reverse flow compared to single check valves. Each internal check opens smoothly under forward flow and closes automatically if the flow stops or reverses, helping safeguard pipework, appliances and system components from contamination or pressure fluctuations.

These valves are widely used in domestic and commercial plumbing, potable‑water lines, heating systems, irrigation setups and general building‑services installations, where enhanced backflow protection is required. Their compact, service‑friendly design makes them easy to install and maintain in both new and existing systems.
