Kayflow Soil Air Admittance Valve – Black

The Kayflow Soil Air Admittance Valve in Black is a precision-engineered ventilation and pressure-regulation fitting designed to manage airflow within a 110mm soil or waste stack. Featuring a secure socketed design, this component is ideal for installations where extending a traditional vent pipe through the roof is impractical, allowing fresh air to enter the system to prevent trap seal depletion while blocking foul odours from escaping.

Manufactured from high-grade, lead-free uPVC and durable ABS internals, this air admittance valve provides a reliable internal pressure regulator, significantly lowering the risk of siphonage and bad odours while ensuring the long-term integrity of the plumbing ventilation system.

Key Features
Internal Pressure Regulation: The engineered membrane mechanism is designed to open under negative pressure to admit fresh air and close automatically to form a tight seal, making it perfect for terminating stacks indoors or in confined roof spaces.

Socket Versatility: Equipped with a precision-moulded socket, offering a snug, secure fit over standard 110mm soil pipes and reducing the need for complex mounting hardware.

Advanced Captive Seal: Features a high-performance rubber gasket that ensures an airtight and watertight connection, engineered to accommodate thermal expansion and contraction.

Durable uPVC Construction: Forged from impact-resistant, UV-stabilised material that is naturally resistant to household chemicals and environmental degradation.
