Brassware - Non-Returning Valve – 28mm

The 28mm Brass Non-Returning Valve (NRV) is designed to allow water to flow in one direction while preventing backflow within the system. It helps protect pipework and appliances by stopping water from reversing through the line, making it ideal for use in domestic and light commercial plumbing installations.

Manufactured from high-quality brass, this valve offers excellent durability and corrosion resistance, ensuring reliable performance over time. The internal check mechanism automatically closes if water attempts to flow backwards, maintaining system protection without the need for manual operation.

Installation is carried out inline within compatible 22mm pipework. The compression connections allow the pipes to be inserted and tightened using compression nuts and olives, creating a secure and watertight seal without requiring soldering.
