Kinetic Air & Vacuum Air Valves serve both to vent air from a filling pipeline, and also act as a vacuum breaker by allowing air intake into a draining pipeline, optimizing pipeline hydraulic efficiency and flow.
A normally-closed, spring-loaded, full-bore Vacuum Breaker Valve is designed to seal drip-tight and to open fully at minimal differential pressure. This protects the pipeline by allowing intake of air into the pipeline or system when vacuum conditions occur.
Combination Air Valves improve pipeline efficiency and hydraulic performance by enabling high-capacity air release and intake, reducing energy use. The FG Flood Guard Attachment prevents contamination by sealing at zero pressure, blocking floodwater from entering the air valve while maintaining its flow rates.
