Backflow Preventer Valve DN50–DN100

Description

1. Product Overview

The Backflow Preventer Valve DN50–DN100 is a robust non-return valve engineered to prevent reverse flow and protect potable water, industrial fluid, and process piping systems from contamination or pressure-related flow reversal. It is widely used in municipal water networks, commercial buildings, industrial plants, irrigation systems, and fire protection installations. Its dependable one-way flow control helps improve system safety, reduce operational risks, and protect downstream equipment. Available across DN50–DN100 sizes, it provides a scalable and commercially practical solution for professional piping projects.
