Straight-pattern storm valve designed for non-return protection in drainage and discharge systems, with an integrated lock feature to secure the closure mechanism when required for safety or maintenance control. Built to prevent backflow and help protect upstream pipework and compartments from flooding when external pressure rises or flow reverses. Ductile cast iron body delivers improved toughness and impact resistance compared to standard cast iron, supporting dependable performance in demanding installations. Designed to DIN execution for PN10 systems with flanged ends for stable mounting, repeatable alignment, and service-friendly maintenance. Commonly applied in overboard discharge, bilge/storm-water lines, and utility drainage circuits where controlled backflow prevention is critical.
