Air Poppet Valves – VA Features and Benefits • Prevents mold damage due to ejection problems with deep-draw or thin-walled parts • More durable and precision-made than competitive units These precision-engineered valves are designed to remedy the vacuum problem often encountered during the molding of deep-draw (e.g., buckets) or thin-walled parts. Air flow, timed to coincide with the ejection cycle, opens the valve to break the vacuum and facilitate part ejection. A precision- ground valve seat helps prevent flash from entering the assembly during injection. Each valve is matched to the body to further assure reliable performance. SPRING SPRING HOUSING Ø E
