The VAG AW Disk Check Valve (Vertical Type) is a durable and robust non-return valve designed for vertical installation. Its metallic sealing ensures long-term operation without elastomer degradation, making it ideal for systems with fluctuating pressures. Equipped with a lever and weight, it ensures quick closure to prevent water hammer and reverse flow. The design supports vertical flow installations and is optimized for reliability in utility and industrial applications.
