PVC non‑return valve designed to prevent backflow in underground drainage systems. This model features two internal flaps, providing enhanced protection against reverse flow, flooding, and contamination. The dual‑flap mechanism offers higher reliability in systems exposed to heavy loads or variable flow conditions.

Each push‑fit socket includes an integrated O‑ring to ensure a secure, watertight connection without adhesives. Manufactured from silent durable materials, the valve reduces noise transmission through the pipeline while offering excellent resistance to chemicals, impact, and soil conditions. The top access cover allows for easy inspection and maintenance.
