Overview

AVG NRIBV-15INV 15mm ½” internal flare (also known as inverted flare) non-return isolation duo valve is Watermark approved. The non return isolation duo valve features a durable metal butterfly handle and an inbuilt one-way check valve which isolates the residential hot water system from the mains supply. The duo valve can be manually switched on and off with its quarter turn ball valve operation, allowing for easy maintenances and services.

The internal flare connection creates a metal-to-metal seal inside the fitting, offering a superior vibration and sealing property than threaded or compression connections.
