Description
Product Overview
The Durapipe AVF UPVC 31NE D/U 310 non return valve is a PVC-U check valve designed to allow flow in one direction and help prevent backflow in commercial plumbing and pipework systems. Ideal for protecting pumps, equipment and pipe runs, it supports safer, more reliable system operation with low maintenance performance.
Key Features
- Non return (check) valve action – helps prevent reverse flow to protect pumps and sensitive equipment.
- PVC-U construction – corrosion resistant and well suited to demanding commercial plumbing environments.
- Double union design – easier removal for servicing or replacement without cutting pipework.
- Designed for system protection – reduces the risk of contamination, pressure issues and backflow-related damage.
Use Case / Application
Suitable for commercial plumbing and building services where backflow prevention is required. Commonly used in plant rooms, commercial water distribution, process lines and maintenance upgrades where a replacement non return valve is needed. Ideal for installations where service access matters, such as tight risers, service corridors and equipment skids.
