Series 24 FlowGuard Wet Barrel Check Valve
The AVK FlowGuard II™, bi-directional check valve, is designed with safety in mind. In the event of a traffic accident, the ball will rise to seal off the flow from the main line. A small stream of water will flow, reducing possible water hammer and indicating the hydrant has been damaged.
